I just put a new voltage regulator on my super c (6 V pos ground).Now it will show a charge,but only intermittently.Is this normal,or should it charge continuously?
Original problem was that it was discharging continuously.Had a brand new battery dead in less than a month .Tractor would also not stay running..is this normal when battery is real low?
Also,how many volts should show on amnmeter when charging correctly?Is it constant or does it vary?How do i check the generator?
I know I'm asking alot,but any help is greatly appreciated.Thanks.

The inside of your generator is probably dirty. The brushes leave a carbon film. Take it apart and clean the copper contacts with some fine steel wool. Check the condition of the brushes while you have it apart.

John - Presuming you have distributor ignition (not a magneto) the motor will indeed quit once the battery runs down, just as you observed.

Normal ammeter readings vary depending on engine speed and the battery's state of charge. At full RPM it will read about +12 to +15 amps with the battery is low and taper to about +5 once the battery becomes fully charged. At idle it however will read -2 to -4 amps regardless of the battery's charge level.

If you are seeing an intermittent charge on the ammeter with the motor running at full speed, problem could be a loose generator belt, poor ground at the voltage regulator or a problem in the generator itself. Suggest checking/tightening the belt then making sure the regulator is base is solidly grounded (mounted to bare metal and mounting screws are tight). If that doesn't correct the problem, use a jumper wire to temporarily ground the "F" terminal at the voltage regulator with the motor running at full RPM. If the problem persists with the "F" terminal grounded the generator needs repair.

Good luck!

Bob M, How dose that work? My C will charge 10 amps at an idle,15-20 at full throttle, and NEVER discharges EXCEPT when the lights are on.(And that's only momentarily, and then it will read 0) And, it dose kick out to 0-5 amps when the battery is charged, and will "kick" the amps from 0-5 up to 10 for a moment, and then back to 0-5 when the battery is charged. I got my voltage regulator from Tractor Supply Co, I wonder if that's the difference? When my C didn't charge when I got it, I took apart the generator, cleaned it, put it back together, and it didn't help, so I bought the new regulator. But in the past, I've had good luck with just cleaning the generator on other machines.
