Thread: Disco ignition problem

I had the same issue in my 94 disco - was the ignition amp on the side of the dissy - there was a dry joint that opened up when cold (Canberra winter mornings). It also cooks in hotter weather in the hot engine valley.

Replace the module and have it moved to near the coil. Post 96 models have it in that position. The wiring loom and bracket to move the module can be purchased or wreckers may have them.

It sounds like you may have water/condensation in the dissy. Perhaps lift the cap up to see if there is condensation inside? If it is, get the engine warm and leave the cap off for 1/2 an hour. The heat of the engine will evaporate the remaining moisture. Put it back on before it gets completely cold again.
Hair dryers are good too if you can't get it warm.

Hi Bee Utey, thanks for the reply, I just checked inside the dizzy cap and it's bone dry.

Not sure if the blowing into the dizzy ever did anything, but unhooking the cap, lifting it and then resealing it seems to get it to go (whereas removing and reinstalling the spark leads doesn't for instance). New genuine cap too. Weird.

Will look into doing the ignition amp replacement and relocation with the Bosch 024 (given it seems a good thing to do anyway), I'll need a new (secondhand) coil to match right?

That reminds me, I did a Bosch amp conversion last Thursday on a 3500 SD1 and I had a bunch of problems getting spark. Turned out to be a loose connector plug on the pickup side. In your case I would suspect the pickup connector behind the amp itself.

If you go ahead with the Bosch conversion you will be in there anyway, just make sure your adaptor cable is a good tight connection. I would suggest a carb Magna, , early Camira coil if you want cheap. Otherwise a MEC 723 off something in that era. I have had a couple of the oil filled coils leak when horizontal, but the plastic ones are no probs. I haven't tried the original D1 coil, not when the aus made Bosch coils are cheap and plentiful in sleazy wrecking yards. I just don't want non-compatible coils with the Bosch amp, I have seen a couple which barely worked at all.

Thanks for the heads up Bee Utey, have just PMed you re the coil&amp replacement option.

Cheers Simon.

Old post I know but just following search, I have VERY similar probs at the moment. Hard cold start-ups (read hasn't today), I have checked plugs & leads & there seems to be a good bright strong spark. The leads are Bosch super sports inductive 010 & the sparks are NGK, it has a blue dizzy cap but seeing as there's heaps of spark I don't think it's in that area.
It just about catches but not quite then floods, can smell it, family car so this is a real pee off
Any other ideas???

ps just had the radiator & engine flushed & cleaned yesterday, radiator was pretty blocked, now this grrrr
