A bare wire caused voltage regulator to burn up. Ordered new after market regulator and had generator professionally rebuilt. Replaced bad wire and installed new Generator and Regulator. Now it will not charge. I remove the regulator cover and pushed the Bat points together and it did charge, but the points would not release and burned up. I cannot get an original Delco regulator as they are no longer available and the new after market regulator supposedly is a direct replacement. I just bought and installed another new after market regulator from a different supplier and it still does not charge. I cannot afford to burn up another $100 regulator. It seems the generator will charge if the bat points are manually pushed, but it will not charge on its own. Even if I push the field points manually it does not charge. This is not my tractor but I was the one that rewired it 15+ years ago and it has worked great until this bare wire caused some damage. I traced all the wired to make sure they were all good and making good connections. I feel it is this after market regulator causing the problem, but do not know how to confirm it. All help will be appreciated.
