97 Disco has blown 6 Ignition Modules, Help

[Halsie]

We have fried/blown 6 ignition Modules (amplifiers) in a month.

Hi, I am a newbie to the Forum and a Yank, (so pardon my misuse of your language )and have been searching and reading posts for a couple of days now. I am in the US and am part of a mission organization in Zimbabwe. We have recently purchased 2 Japanese Disco's a 97 Model E-LJR / Chassis # SALLJR-MM3TA193707 and a 98 Model LJR-SALLJRMM3WA761853 Both 3.9L GEMS Type engines. The 97 has gone through 6 ignition Modules to date and has been towed to the Capitol City Land Rover Dealer for the 3rd time. The Coil has been replaced as it was thought to be spiking voltage. A new Fuel pump (BOSCH). I can't be sure that the dealer supplied the correct coil for the modules, but must assume so until otherwise confirmed. I have sent the info regarding the voltage to the coil with the ignition on and off

My automobile experience is with 60's vintage Pontiac GTO's with points. I think there is an issue with too much voltage, too much heat and or insufficient grounds (earths) I also am very interestedin the excellent article by" bee utey" on the conversion and remote mounting. We have traced all the known electrical grounds (earths) and found one faulty one at the fuel pump.

The problem is that I am in the US and leaving for Zimbabwe the end of May so I am collecting diagnostic info to pass on to my Zimbabwean friend to solve this problem before we arrive so as to have transport.

I am appealing to the vast knowledge here to help figure out this problem. Any information will be most appreciated.

Thanks,

Hal

Hi Hal,
While there may be overvoltage issues, the Lucas style original ignition amp has been marginal since new. Aftermarket replacements are worse. The most likely problem I would imagine in your case is that a non-compatible coil has been fitted. The Bosch conversion I have developed is good as it uses locally (Aust) available parts. In your case I would suggest you contact Crane Cams in the US as they have a range of ignition amps available. They should be able to advise the most suitable unit.

Crane Cams | High performance multiple-spark CD ignition for racing or street (http://www.cranecams.com/view.php's_id=15)

Probably this unit: HI-6S and LX91 Coil Kit – Universal Applications

Before I developed the Bosch conversion I used quite a few Crane points conversion kits (XR700) and they were quite reliable.

I have seen (Ebay) aftermarkets last exactly 5 minutes from new ... If you intend on using the original AMP ... make sure it's got the original coil


I'ld do bee utey's conversion ....

Sorry for not replying sooner. My wife and I got hit fairly hard in numerous tornadic thunderstorms Wednesday evening in Tennesse. Flooding, hail dinged vehicles etc. We are safe, but have been dealing with the mess for 3 days.

I am looking at the Crane site now. TO be sure that I undrstand what you are saying. I nee the XR 700 ingnition module and optical trigger plus an installation kit. (Part No 700-2300 for Lucas) Correct?

I also can use your Bosch Conversion? I am not clear on the availablity of the Bisch parts (I haven't searched).

I highly suspicion a mismatch between the Coil and the Module and or the aftermarket module (which I will admit was ready to purchase).

Thanks.

Hi Hal,
I suddenly thought a multiple spark unit would not suit the Disco unless there was an adaptor to run the pulse for the ECU. I am sure Crane will point you in the right direction.

You should be able to purchase suitable Bosch parts online through ebay. There is a coil here:

and a module/amp here:

The conversion is quite easy to do, 4-5 wires, and a suitable heat sink for the amp to be screwed to. PM me if you need help finding Bosch parts as I have made a few of these kits for forum members.

Sorry to hear about your tornado problems, it seems to have been a bumper year for bad weather so far.

I would prefer going the Bosch route. I would like to find these parts nearby in the US if possible. When I search here, the parts places want to know what it's for meaning the year, make, model and engine.

I looked at Nissan Maxima 6 cyl and a Pathfinder but the modules looked way different with more than 4 pins. (they aren’t # of cylinder specific are they?)

Could you tell me the autos that the 024 is designed for? Would I also be correct that the coil for that vehicle would also be compatible?

Your information is very much appreciated.

[mike 90 RR]

They are from Australian (main stream) cars

I wonder if this is the US equivalent? .... at 15 bucks a pop .. :)

The Bosch 024 module was fitted to carburettor cars from all the major manufacturers (GM, Ford, Nissan, Mitsubishi, Toyota) in Australia between 1979 and 1987 approximately. I believe this was one way to increase local content and Bosch had a suitable HEI distributor design to go around. Some Aust models may have been exported to South Africa, so possibly you could find some there.

There may be other compatible modules out there but the 024 requires no special connector plugs to use, so has been my choice.

You may also be able to find some Chev ignition modules/amps, used on their coil-in-cap distributors. I have used 024 modules to repair these in the past, so they are very similar in function.

Just found some in the US:

Now we may be on to something. I have the HEI Distributor with coil in ti from an 84 Pontiac Gran Prix. I may actualy have the module too. That would be a stroke of good luck for a change

I will assume that the G is the Ground/earth. The W; 3; 8 ?

Would this module or the Bosch work with the Coil that we have (if it's an original Lucas or direct replacement, I believe the whole mess is a series of mismatched coils to modules/amps).

I will try to find my parts tonight and see if my wife threw it out or not :-)

Thanks guys/mates!

Ground is through the lower mounting screw. W and G are from the pick-up coil and probably refer to factory wire colours. Note they have the same small/big connectors as the Bosch. They may be the same, but it's easy to swap the pickup connectors if the firing point is all wrong, as per my Bosch upgrade thread. B and C refer to battery(+) and coil (-) I believe. Instructions should be available on the magic wwweb I imagine. Ask a supplier about compatible HEI coils in the US.

BTW a word of warning. I suspect cheapie chev modules may suffer from Lucas disease too. The last Chev HEI distributor I replaced the module on had been fitted with 2 aftermarket modules in 3 months. So seek genuine or reputable modules if you can.

I just checked my dissy (84 GM HEI) and the module/amp has 7 terminals and appears to be run off the ECU.

I will get to a parts store this week (travelling the next 2 days) and see who manufacture the ones they have and also check a wrecking yard or 2.

Looking at you picture where you made 3.2 mm crimp connectors. Is the amp removable without removing the dissy? I want to build the unit here and take it with me. (You mention your Bosch update post, is that under the Original post as a replyin Feb?)

My dude/mate in Zimbabwe suspicions the ECU is faulty. From what I am seeing here, the Bosch conversion doesn't appear to rely on the ECU in out 97 or 98 Disco. IS that correct or does the ECU supply a signal? and do you know a source for a Jap Disco ECU? (I'll be there 6 weeks and then back to the US). I am bringing a faulty alternator back for a local rebuild by a fellow I know that builds bullet proof ones.

You are giving confidence to go for it! The nervousness is in that we may have to travel to Botswana or further to South Africa to get parts there.

Thanks

The Disco ECU takes the signal from the coil, not the other way around. The 97/98 Disco has a harness from the dissy to the amp/coil set mounted next to the radiator. You cut the red and blue wires off the old amp plug, terminate them with crimp connectors, fit them to the new amp/module. Earth the shield connector to a screw on the new module.

https://www.aulro.com/afvb/


The connections from the original vehicle wiring go back on to the coil you choose, as do the B and C wires from the module. I have no information on whether the original coil will run on the new amp, I simply haven't tried. Don't like to mess around when I have a reliable set-up.

The dissy connecting harness remains unmodified, only the short piece between the plug and amp. You will need to obtain suitable screws and a thread tap to modify the original heat sink that the blown amp is screwed to. Oh, and make sure you have replacement heat-sinking paste available. It is VERY important. It should be packed with every new module or available from parts shops or electronics stores. It is sometimes used for mounting power transistors.

Couple of Q's

Where exactly have you been buying these 6 modules ... and were they genuine LUCUS?

Is your mechanic putting / using / Installing the heat sink paste to the back of the module, when bolting it back up to the heatsink?

Exactly which coil are you using?



IMHO ... I doubt the ECU theory ....

Ok I am going to re-check with ZIm and clarify that the current module is not attached to the dissy. I was under the impression that is was on the dissy from their information to me.

I found some engine ECU's at Roverland, so hopefully we won't need one, pricey.

Well midnight here, so I'll be back online Wednesday from Sunny Florida.

Thanks Mate! (is it ok for a Yank to call you Mate?)

From what I know, the Land Rover Dealer has replace 2 or 3, not sure about the others. As for the paste, I'll ask that too. Thanks

Information from Zimbabwe is slow coming.

The woed I got today is that "they (Dealer was involved in a couple)" say they were using "inferor modules/amps" to which I would reply "duhh". They are ordering one for a Toyota something. More as I learn more.

[Halsie]

Hi again:

Finally recived the answers to my questions from Zimbabwe.

The Coil and module/amp are near the radiator as bee utey said they were.
The replacements (some by the dealer) were "inferior" and they have ordered a Toyota Module;

I plan on persuing the GM module that appears to match the Bosch (see bprevious posts).

From these diagrams I think the following is true: (Bosch to GM)
3=G
7=W
15=B
16=C
Correct?

If this is the same as the Bosch, is the stock coil compatible?
Or if not, I read the post re: HEC and MEC and do not see that on any of the Coils here. Also something about not being a Hall Effect Dissy but a variable reluctor. Not real sure what to tell the parts guy.
https://www.aulro.com/afvb/images/imported/2011/05/896.jpg
https://www.aulro.com/afvb/images/imported/2011/05/897.jpg
I recall reading something regarding a ground/earth wire from the grounding lug to the dissy?
https://www.aulro.com/afvb/images/imported/2011/05/898.jpg

Also are the Dissy connections color coded? or looking at the diddy which terminal goes to the left and which to the right. I am contemplating putting bullet connectors in line so that I can build modules in the states and make installing them easier (will do both Discos in the October if this works with the GM)


Thanks for your help, we leave in 2 weeks.

Just try the GM module on the OEM Rover coil. One forumite here recently reported his OEM coil running well on the #024 module for at least the last month.

Your wiring looks about right. On the Bosch 024 module the original pick-up wire is blue to #3, red to #7. Then there is the earth shield (black) that goes to a mounting screw on the module, as per pics in my post below. The simplest method I think is just to install the GM module to the heatsink that the original Lucas amp sat on. You will need a short 2 core patch cable from the GM amp to the coil, insulated female spade connectors at one end and 5mm ring terminals at the other end for the coil. You will need 4mm bolts and nuts long enough to secure the new module to the heatsink, and a drill bit for the heatsink. And two crimp terminals for the #G and #W connections.

I recently purchased a GM module off ebay which I might test on an OEM coil for something to do. Something to do in my spare time, I guess.:cool:

Let me see if we are talking about the same thing. When you say a short 2 core patch cable, do you mean 2 wires, 1 each for terminal B/ 15 & C/16. each with a ring terminal on the coil side and a female spade on the other?

I've looked at this picture a dozen times and finally see the module, duhh. It looks like there are 3 wires in the Disco harness, red, blue and black. The black wires is the earth and runs to the earth mountin screw, correct? 97/98 is 2 wire?

Do you know the size of the terminals in the 97/98 Dissy wiring? Do I need to get corresponding male or female terminals to attach?

I may luck out and find a matching connector, does it have a name or other application?
https://www.aulro.com/afvb/


I may purchase a spare Coil anyway and I will ask about the MEC type. BTW Does HEC refer to Hall Effect Coil? And what does MEC stand for?

I do belive that I have 90+% now. Thanks Bee utey!

[Halsie]

As I look at the various picture, I begin to see other things that I want to clear up.

DO I need a capacitor? What spec or are they all the same?
I am not sure if our coils is round or not, but I suppose a holder would be in order too.

Besides wiring, what else do you think I might need to get before we leave?
Thanks!

Look I don't do complicated. Just cut the **** plug off the Lucas amp short connector cable and crimp 2 lugs on the blue and red ends. Like in the picture. Or find a wrecker and buy the short bits and crimp them up yourself.

Bosch-speak for high energy, medium energy, coil. It's part of their part numbers. e.g. MEC723. Coils can't see what type of sensor your dissy has, the module sees the sensor. I can't tell you what to buy, find a shop keeper who knows about coils for 80's cars with electronic ignition. Bosch list a cylinder coil BIC290 that some people have used on Discos. Not me.

Oh and the capacitor is a radio noise suppressor, the one already attatched to the disco coil will suffice.

This afternoon I picked up a module and an Accel Universal Coil, tube of dialectric grease for Heat sinking.

Thks is the coil SUPER STOCK COIL-POINTS - ACCEL Coils & Accessories - ACCEL (http://store.prestoliteperformance.com/accel/accel-coils-accessories/super-stock-coil-points.html)

Yes it says points, but my parts guy says it's a universal:

Rated at 42,000 volts
Great for points ignition systems
ACCEL's Super Stock coils are high-performance replacements for OE canister style coils. Improves starting, idle, throttle response and top RPM power. Works with OE ignitions and computers. Alkyd tower prevents flash over.


Accel makes a model 8145 that says for breakerless, (not in stock, but can order).

Thanks

You do not use a points coil on electronic systems. This coil is only universal for all points cars. Buy the one for breakerless systems if you have to.

This is turning into bigger than Ben Hur :(

Using super duper coils will take out and burn the original LR spark leads :twisted:






Given the location and the quality of the local Trades and Services of where this vehicle is located ......


I would stick with the ignition amp that Bee utey has pointed you to, Replace and use the original LR coil + use a good set of spark leads

Bee utey uses Bosch gas leads, I use Champion SS gas leads ... In the USA, you have a brand called Magnacore.
Use either the NGK or Bosch standard spark plugs



..... Always try to stick to the KISS method ....
If you keep it simple, then it is much easier to service these parts at future dates ....
If you make it complicated with aftermarket parts, then your future mechanic will be "lost" :confused:

I will trade coils for a breakerless ignition. The guy that helped me today doesn't know what you guys know about what we are doing, but he went right to the bin and pulled the module I wanted. All the other fellows couldn't do that because that module wasn't for a LR.

THe coil was WAG, not a SWAG, so we will trade it for a closer to stock coil as it's really a spare.

I will get pretty familiar with the Disco for about 6 weeks and if things go as planned, I will make an additional 3 conversions for our 2, the hosts and one for a spare.

Cheers and GBU

Hi Mates,
I am back in the USA after being in Africa 6 weeks and wanted to give you an update on the conversion. It went well, no more blown modules and at a cost of under US$40 per conversion using a GM Early HEI Module due to the unavailability of the Bosch.
Thanks bee utey and the rest of you.
I have pics, just don't know had to insert.

Excellent!

I haven't yet tried the Chev module I got, I've been too busy. Good to know its working.

As for pics, use the "manage attatchments" button to download pics from your computer. The button is about 2" below the "submit reply " button, in the "additional options" field.

Ok here's my attempt at uploading the pics.

Your's truly
Team; Module mounted on additional heat sink made in US prior to departure; Complete setup monted on original heat sink (heat sink grease between module and pre-fab additional sink and again between the original.

SInce I won't be going to Africa on each trip, I have attempted to simplify the installation and ease of replacement with the harnesses.

Again heartfelt thanks from the 28 people that relied on our 2 Discos for transport in May - July and the 25 scheduled to go in Sept-Nov.

Cheers and GBU

I chucked it all and fitted a Scorcher. Just plug and play.

I've also used an early v8 SD1 Lucas electronic (Opus) dissy fitted with a Lumenition module and this worked well. The dissy drops straight in - swap the springs and weights in out of the Disco one if you want to retain the same advance curve.

A cheaper option these days with the higher Aussie dollar may be to get a Buick/Rover MSD dissy complete - comes with adjustable advance curves.
