I know this may get deep in a hurry
I ham having charging problem on my 64 cub. Have followed the generator troubleshooting flow chart. when doing step 3 found that when junpwe is put on the Bat to Gen terminal the amp meter will jump every once and a while to the charge side but stayes on the discharge side most of the time.
Now here is the question
I have a old regulator that have already taken off the tractor. have looked at it and can see that is is basicaly two relays that work together to sence the voltage and change there operation when the voltage is high or low.
Can anyone give the correct discription of operation so this be used in troubleshooting this kind of problem.
