faulty coil or moduel???

Post by gumtree »

my dads 92 laser with a 1.6 carby engine wouldnt start yesterday and we figured it was a faulty coily and the racq towee suggested ignition moduel. put i a new champion coil today and it started, ran for 1 minute then stopped again and wouldn't start again???

so as i dont know a great deal in this area is it a faulty new coil or is it the moduel? why did it run for a minute then stop?

advice greatly appreciated.

Lasers are notorious for doing the ignition module. They often don't fail until they get some heat in them. You can get them from Repco.

I have the same problem with a '93 magna.

Ignition modules for these older cars are relatively cheap however, they dont seem to last long.

Does anyone have any advice as to why?

I also noticed once it stopped running properly, if i let it cool down it'll work for a minute or so too, sometimes 5-10 mins.

I take it once its cooked its stuffed? anything I can do to prevent it cooking ?

They are cheap but inconvenient buggers to replace :)

Sorry if this is Off topic.

when replacing them ensure that you use the paste that is recommended for the module. it helps to transfer the heat out of the module into the dizzie.

It seems when I buy the modules they come with paste, however over time it seems to melt away leaving it dry and causin the module to malfunction.

Does anyone know where I can get similar paste? I tried dicksmith and jaycar, but its too thin and just melts off.

Just wondering if anyones tried relocating the module and a way to keep it cool?

maybe this is just a magna thing, after all its a cheap piece of crap :)

Know SFA about Lazers but amputated the module of my jap dissy and used a remotely mounted BOSCH module and HEI coil...

Shielded lead required from VR pickup to module but works like a charm with significantly higher discharge energy and IMO the particular BOSCH module / coil is a much better unit.

This could all be useless to you but for what its worth......
( usual disclaimers )

It seemed like a much better idea when I started it than it does now.
