Charging problem

Postby Coventry plumber » Thu Jul 27, 2017 3:38 pm

I need some help with a charging problem. First off I am restoring my 52 cub . I'm at assembly stage. New wiring, new coil , new regulator . The generator has been rebuilt . So I have power to the battery terminal on the regulator but nothing at the generator terminal on the regulator . I installed a second regulator figuring I did something wrong and wrecked it . But still same problem. Looking for guidance on finding my mistake . Thanks

Did you polarize the generator after installing everything and before doing any testing? Engine running when you checked voltages? At what speed? Did you try measuring it with the generator "F" terminal grounded? The gen terminal won't show any voltage unless the generator is up to speed and producing something.

I did polarize first , then with the engine running at just over half throddle I tested . Shows slight discharge on the amp gauge in dash pedestal. I'm not sure what you mean when you say ( F terminal grounded). Thanks

Disconnect the "F" terminal, then remove the belt and jump the battery and "A" terminals together. The generator should spin like a motor. If it doesn't, make sure the battery terminal on the regulator has battery voltage to it. While you have it motoring, ground the "F" terminal. The generator should slow down but continue to motor. If the generator does all of that, it's OK.

Great! There's nothing better than when you finally figure out a frustrating gremlin.
