Can't find original Post.

40 Coupe, 48 block, Petronix.
Had the car re-wired last fall with all new harnesses.
Car has never (4+ years) showed in the green on the voltmeter. Used to run on the low end of the yellow, This April it started at about 3/4's on the Red, ran fine. Then about 1/2, skipped and not full power.
Had the generator re-built and matched to the regulator, Same thing. Took it back and he assures me it's putting out 7+ volts and 30 amps.
Had someone help with a voltage reading today from the Batt terminal on the regulator to ground. .2 Volts. Battery stays charged.
Right now I have an expensive piece of yard art.

Any help/suggestions appreciated.

Paul if it was me I would retire the entire generator system and simply replace it with a 6 volt alternator. The common GM Delco alternator can be converted to 6 volts with an internal regulator there's conversion kits available to do it. Or look at what Speedway offers they have a 6 volt single wire alternator that will work perfectly as well. Going to the alternator you now have a one wire system just one wire coming from the alternator is now connected to the battery.

Fitting an alternator may not fix any of your problems, just skirting them possibly. Fix what you have and learn by it. Why have you started a new thread on this subject ? Regards, Kevin.
