Electronic Dizzy

[chev28]

Any thought?

I have just put an electronic distributor on the 3Y motor(replacing the old point one). Runs well (no different really but hopefully will stay in tune).

Should I bypass the ballast resisitor and run 12V all the time or continue as for the old coil and run through the ballast resistor and thereby run 6-8V after starting?

Anyone tried this sucessfully?

Thanks

What coil are you using? The original that's designed for the ballast resistor?

[chev28]

Good thought David but Toyota put the coil in the distributor for the 3y. I noticed that the tarago, etc use the ballast resistor so maybe I should go along woth that. It runs well enough through the ballast resistor. I just know that some Holden electronic dizzy upgrades run without the ballast resistor and supposedly get better spark.

I'd be a bit wary of running without the ballast resistor. The coil will run really hot and I wouldn't expect it to last very long.

Getting rid of them points will be such a bonus. I did the same thing to a Gemini many years ago and what a difference it made. Like you say it doesn't go out of tune.

Still lookin for the distributor and points on the diesel Rocky - must be there somewhere.

Sounds good, I'll stick with the ballast resistor. Don't want to have to replace the whole unit for a burnt out coil.

The coil is built into the distributor?! What a strange design..... Does the coil lead run internally as well to the cap somehow?

Definitely keep the ballast resistor if you're running a coil designed for one.

True, it is a strange design. The distributor has a bit of a square buldge on one side where the coil is housed and the cap does have a circuit for the coil to rotor centre. Quite a bulky thing really.
