I finally found my problem. There are several sites that suggest unplugging the regulator/rectifier connector and checking stator output with engine running full speed. That's fine and well but you should then turn the engine off, reconnect the regulator connector, start the engine, run at full...

Put the 2nd 'new' regulator on and got the same result. Battery voltage started at 13.2. Started the engine and voltage dropped to 12.5. Guess it's not a regulator problem. I'm looking at the grounding possibilities now. Thanks ILENGINE and slomo for your advice.

It sure looked like a bad regulator to me, too. After trying 3 different regulators though, maybe not. I have checked that the regulator is grounded, 0 volts from regulator case to engine block, also 0 ohms. Have also checked connections between battery posts and their respective clamps, and...

Hi slomo and thanks for your interest and ideas. I use a Fluke(which the name doesn't reflect on the meter's performance), digital multimeter for all measurements. If it reads 0 ohms, there's no resistance. For both you and ILENGINE, I just pulled the flywheel and checked the magnets. No loose...

Ok. Just tried another battery. It had 13.11 volts with the engine off. With the engine running, it dropped to 12.74 volts. Different numbers but same result.

Yep, don't think I'd have 28 vac with loose magnets, may pull the flywheel just in case. First, I'll try another battery. Thanks for the idea.

I ran a jumper wire from regulator 'B' terminal to the battery +. Used a Fluke digital multimeter to check the voltage. Before cranking, I had 12.01 volts on the battery. With the engine running, the voltage dropped to 11.85 volts. This was the result with or without the jumper from regulator to...

Thanks for the reply. I've checked that the regulator is grounded and the ground wire is attached and properly grounded, 0 ohms to ground. I am getting battery voltage to the regulator 'B' terminal. I'll run the extra wire from regulator 'B' to battery + and post results.

Hi to all. I'm trying to refurbish this old JD that my mother used. I've got it running and all the belts replaced. My situation now, and for quite a while, is that the battery isn't charging. I am getting 28 vac out of the stator, which I think is normal. The voltage/rectifier only puts out...
