Thread: Ignition module 3.5 V8

The original Ignition Module uses the dissy body as a heat sink, it has thermo paste between it and the dissy body to help dissapate the heat, if you mounted it on the inner guard did it have any contact with the guard to dissapate heat as it is supposed to do on the dissy body, I would check to see if the New Module is supposed to have a heat sink to get rid of the heat, Regards Frank.

The Land Rover module I used was from a later Disco and was mounted on a factory heat sink, a large piece if thicK aluminium. I mounted this to the inner guard near the coil as the factory do.

The new Bosch module is mounted also on a piece of aluminium with the thermal grease that comes with the new module. It is then mounted to the inner guard.

I am pretty confident this will work OK.

I do suspect that the original module is getting to the end of it's life anyway.

I'm just glad to find that in the middle of nowhere ... there is a alternative to use

The Bosch HEI module for Commodores and Falcons from way back are carried by RACQ Patrols...at only about $50 a throw. They work fine on the 3.5 and 3.9 Discos. Its the Dizzy itself that often lets the LR V8s down...I ended up replacing mine on my 95 with a Ford/Holden homologation from Performance Ignitions....holden V8 button and cap and Australian Bosch - Ford - internals including HEI Mod and pick up.,

Cheers

Off the subject a bit

Does anyone have a faulty module that don't need any more as I require the housing to do a mod for a remote set up

I recently had the same problem.
Replaced module and coil with new LR bits from Landrover Spares here in
Mackay.
Now runs beautifully once again.
Had to take the wife upto Townsville Hospital the other day and it was
a good comfortable trip with little trafic both ways.
My little Bird had a ball.
Went up there 12 months ago and averaged 17.5 lts per 100, this time,
14 lts per 100, very pleased !! Nine hundred K round trip.
Cheers.

If you are going to gut the housing be carefull as I believe they contain beryllium which is carcinogenic.

About 1-15% of all people occupationally-exposed to beryllium in air become sensitive to beryllium and may develop chronic beryllium disease (CBD), an irreversible and sometimes fatal scarring of the lungs [More...] Occupational exposure most often occurs in mining, extraction, and in the processing of alloy metals containing beryllium. The adverse health effects of beryllium exposure are caused by the body's immune system reacting with the metal, resulting in an allergic-type response. The following references aid in recognizing hazards and health effects associated with beryllium.
