Thread: 97 Disco has blown 6 Ignition Modules, Help

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!

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?

Yes

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 mounting screw, correct?

Yes

97/98 is 2 wire?

Same as picture, 3 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?

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.

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?

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

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






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"

Thanks guys, especially for the patience with a newbie to LR's.
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.

Halsie

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.
