My 48 Super A was switched over to 12V by a PO and operated fine until last year. The chevy alternator quit working, and I was relying on the battery charger to keep the battery up. I replaced the alternator and had the battery checked (ok). As far as I can tell, the alternator is not charging the battery. There is a button on the dash, the PO called it an "excitor"? that you had to push, then the amp gauge would jump to positive charge. Since the alternator has been replaced, puching the button actually causes the needle to go negative. I know I replaced the wires exactly as tey were before. What should I be checking next? Where can I check the the voltage safely?

After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
