Thread: Disco backfired this morning on gas :( What to do?

Just jam some wire in the coil output? Wouldn't it just spark to the chassis? Coathanger wire or doesn't it matter so much? How long would a coil typically last on one of these before you'd get suss on it? There are a few rounds of drinks on me if I ever meet up with you guys, thanks do much for all the continuing great info

Mate - I had no end of problems with my 95 3.9 and tried replacing all the gear with stock gear, gas gear you name it. Over the years it became apparent that the lucas dizzy can have no noticeable shaft play but still throw errant spark on its parade test....result backfire....so out it all goes and in goes a Schorcher Dizzy made in Oz with all GM and Ford and Australian Bosch bits and a set of leads from the same place in Melbourne and a coil from the same place (resin) and.....runs better than it did off the production line and LPG is a beautiful thing again (for the last 20k since I did it and very confident having owned australian cars with electronic ignition before).

Cheers

Nah mate, the wire thingy is a precision output voltage measuring device, subject to patent protection in 33 countries, including Nigeria. 12mm gap is sacrosant, otherwise you burn the coil insulator. You can either buy a suitable paperclip off me for $3000 or send me my commission via Western Union

Hahhaha okay well you just give me the details and I'll paypal you for the paperclip...only thing is I need it by the weekend

I like the idea of just getting rid of the Lucas dizzy and putting oz parts in. I've overhauled and replaced the ignition with an electronic ignition in an old ford I used to own (which always had tuning issues) and that together with a new coil meant that lpg performance was beautiful and it didn't just go out anymore...maybe I'll do the same.

Ozscott, would you be kind enough to put up a list of the actual parts you ended up putting in your Disco pretty pretty please If it worked for you then I wouldn't mind giving it a go too since I'm going to be putting new bits in my Disco anyway.

YA, check out Perfromance ignitions in Nunawading. They have replacement scorcher Dizzys there. They make them up from Aussie parts.
About $660 and about $60 extra for the electronic Bosch coil.

Sounds good...although expensive. But really the piece of mind that would offer would be great! I think that's the one I just found on the internet. Would they put it in and tune it up for me too or would they charge through the nose to do that as well?

Also I see they are Bosch stockists...would their Bosch stuff have some crazy markup on it because they are a smaller more specialized shop or has anyone bought from there and found their Bosch prices to be just the same as the big stores?

I have found Performance ignitions very good to deal with. They really know ignition systems and what works. They put me onto the Bosch rotor that Bee Utey now recommends. I got all my Magnacore leads, Rotor and Vacuum advance from them and found there prices very good. You can get the standard distributor working sweet. Mine is running like a dream on both gas and petrol ( Touch Wood!!! ). Give them a call, They are happy to answer your questions.

As said above they are great. I threw new pick up coil and plate, amplifier modules, caps, buttons, coils, leads etc (all lucas and genuine) and it didnt provide anything like a long term fix...did the perfomance igitions Scorcher as said above and all is well...now just pick up holden bits like rotor button and cap if you need it and the amp module is $40-$50 from an RACQ breakdown patrol who stock them if you every need that gear but knowing holden like I do you will probably go 10 bloody years without needing to do button and cap and amp.
