Another A farmall charging problem

Posted by Terry on July 01, 2003 at 21:32:10 from (67.250.216.145):

I have a 1940 A Farmall with the cutout.

I am having trouble getting it to charge correctly. At half trottle and above it puts out 5 amps.

With the digital volt meter, the reading jumps all over the place between 7 and 11. With the analog meter, it shows around 5 volts.

When I ground the field terminal on the generator the voltage appears to stay the same but the amperage increases from the usual 5 to 10 amps.

I took the generator apart. The brushes looked like new but the communtator had grooves in it. I sanded it and cleaned the space between the bars. I put it back together with the old brushes. It still acts the same way. Would new brushes correct the problem? Go ahead and chew me out for not putting in new brushes, I got it coming. Just didn't want to make the trip to town.
