ground the F term, but if you run it to long that way it can damage the generator. With out the battery for a load they can go up to 40 volts or more.

As John said, you will not get a generator output until you ground the field to tractor. You can check the generator with the wires off as follows. I recommend that you repolarize the generator before this test by briefly touching the armature (A) terminal with a jumper from a battery lead. Then conduct the test by preferably using an analog rather than a digital multimeter. Connect the black terminal of the meter set to test voltage to the armature (A) terminal and the red end to ground on the tractor. You should observe a very low (maybe half volt or so) residual charge on the voltmeter indicating that the armature is polarized. Take a jumper wire and connnect it from the field (F) terminal to ground. Now start the tractor at the lowest idle and gradually increase RPM while watching the voltmeter. Volts should rise. There is no need to let the voltage go much over 8 volts since doing so for any length of time could overheat and damage your generator. If your generator responds, it is working fine.

I think I will take my battery over and have it tested then have my generator tested. I will get a new voltage reg. at Napa. I'll let you know how things work out. Thanks, Bill

Napa checked battery(Advance Auto wouldn't check it), battery bad. I ordered a voltage regulater, will be here Tuesday. I will let you know how that works out. I ran the motor test again per your instructions, gen. ran both ways.Thanks for all the help, Bill
