Thread: 97 Disco has blown 6 Ignition Modules, Help

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

Probably this unit: HI-6S and LX91 Coil Kit – Universal Applications
6000-6305

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 ....

Thanks bee! (and MMEJ and Mike 90 RR)

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.
Hal

I now see your parts recommendation, I will call Crane Monday and confirm for the 97 & 98 Disco's. I will reply back with their comments.

Thanks again bee

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:

ELECTRONIC IGNITION COIL BOSCH TURBO PERFORMANCE MEC717 | eBay

and a module/amp here:

IGNITION MODULE FORD HOLDEN MITSUBISHI NISSAN BOSCH 024 | eBay

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.

Many thanks.

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.

They are from Australian (main stream) cars
