Pretty sure they didn't from about 1960 onwards.Just coil points and capacitor.

Sorry, red motors did.Did not realize the wire was the resistor!!!I've always wired up with relay like in the diagram.
[quote] This circuit uses a Ballast Resistor in series with the Ignition Coil. In Holdens, from red six powered cars onwards, the Ballast Resistor was incorporated into the wiring harness and was a pink coloured wire, printed on it was "Resistance - Do Not Cut".on every Holden wiring harness I've repaired this wire has melted through in one spot or more, and I suggested to the customer either Electronic Ignition or an external ceramic ballast resistor, If the harness was removed from the car I would remove the wire, otherwise I would just cut it at each end and leave it. Its not a very smart design, running a wire that WILL generate heat in a harness, and It isnt even fused. Holdens that were equipped with Grey motors had no Ballast Resitor in them. At Idle the Ballast Resistor heats up and prevents the Coil from overheating because the Coil has more time to conduct current. As the RPM increases the Ballast Resistor cools down and allows more current through to the Coil to compensate for the reduced time available to charge the Coil. When a single pair of Breaker-Points is used the system needs a 50% duty cycle. i.e the points close for the same amount of time that they are open. With these points there is little lattitude with this and a change in Duty Cycle will result in diminished Coil output. [/quote]
Modded & fitted a Valiant electronic ignition dizzy system for the 186 I had. Worked pretty good. The guts was the same as the holdens & just swapped the guts/ bodys over

And the only others I've seen with the resistor must have already been done, and it was a 10w ceramic zip tied onto the side of the coil.

just a case of finding one tho, still hunting for a weber and now a dizzy, what sort of coil am i going to need!

GT40 from repco.

bought a zg fairlane, the guy I got it off had bought an aftermarket coil for it and a ballast resistor had come in the box with it, so he installed it. never thought much of it until I was driving on a wet night, wipers and lights on, if I hit the brakes the car would stall. between the ballast wire and ceramic resistor I was losing that much power to the coil that current draw elsewhere would starve the coil. took a bit of head scratching before I clicked admittedly haha

I use a bosch hei coil from the local auto sprkys

would a 253/308 HEI dizzy work if i changed the cap and possibly some internals! its the only distributor i can find at the moment.

patience son, one will pop up, ask at your local wreckers, much easier to just start with the right part.

theres alot of different versions that will fit tho! il try source a few part numbers, might make it easier to order something from bosch directly

I found my resistor wire partially melted almost the whole length! Cut it out, fitted GT40 with ceramic resistor from a Summit Racing coil I bought online, the SR coil soon shit itself, so went with the GT40, have since been checking out coils and ignition boxes from Mallory etc, but according to 'experts' the Bosch is the best option. Yes, the V8 dizzy is the same, you might have to change a few pieces but it will go straight in. Use the HEC 716 coil with it. although apparently there is an upgraded version I've yet to find. The Weber from a 2ltr motor will do the trick as the engine bore size is almost the same. Don't go Holley, unless you find/alter a manifold to get the throttle shaft parralell with the head, 'regular' Holley fitting-90 degrees to the head, exacerbates (big word eh!) intake flow, hurting distribution and power.

There is a website called 'How to Build a High Performance Holden 6 Cylinder'. or words to that effect, BRILLIANT READ! Loads of info regarding all aspects of making power. HIGHLY recommended!
well i think ive sorted a weber. turns out a mate of mine has a few laying around and is finding me one today. so my next find will be a gearbox to replace the trimatic i have bolted up. prefer to stay with an auto as il be tempted to thrash a manual. i would like something to bolt straight up but not worried about small modifications. ive been told powerglides may be the go! any ideas!

powerslides are only 2 speed arent they! always the old borg warners to bolt on I suppose. whats wrong with the trimatic!

its only got 3 gears lol. i would prefer something thats not going to left me down. im unsure of the trimatics reliability.

you got that carb yet! which model did he have for you!
jezz43,
Jul 5, 5:21pm
no luck with a carb yet. have given up on it. im going to rip the engine out and pull it apart this weekend to have a good look at it. then il rebuild and sit it aside while i finish the body work.
xacoon,
Jul 5, 5:30pm
fair enough. give you time to sort out the ignition and stuff too I guess
jezz43,
Jul 5, 5:34pm
at this rate, il end up canning the 202 and going with a 3.8 VN motor. i cant be bothered hunting anymore lol. the body work should be done in the next week or 2 so after that if i havent got what i need il go another way
xacoon,
Jul 5, 5:43pm
oh ye of little patience haha. I reckon thats half the fun of a build is finding those elusive bits
jezz43,
Jul 5, 5:45pm
well i was originally going to go with a 308, but i cant find one anywhere thats not completely rooted and in my price range. i dont mind buying something to work up,i just hate not seeing progress
