I have a '63 Ford 2000 that has had a 12 volt conversion, and the battery discharges while running. I have wired and rewired by different reccomendations and still have the same problem. I have always had to disconnect the battery when it's parked because it drains then too. The original 12 volt conversion had a Chrysler alternator and Voltage Regulator, I have changed over to the GM alternator and done away with the voltage regulator and rewired the whole charging system. I have apparantly done something wrong, can anyone give me any advise?

IF I knew how you have it wired, I could likely see the problem, but as one old fart likes to say, 'I don't have a crystal ball'........got a diagram of your wiring??

With the Delco internal regulator alternator, following the wiring diagram in the link below should help you wire it correctly.

If it kills the battery when you shut it down, sounds like your #1 alt wire is connected to constant power, and is not turning off with the ignition switch as it must.

Also, it showing a 20 amp discharge while running, MAY be a discharge, or really a charge if the tractor was switched from pos ground to neg ground without switching the wires on the ammeter from side to side (post to post).

If the ammeter is connected wrong for the battery polarity, it will indicate a charge as a discharge.
One way to determine that is to switch on a load with the engine stopped(lights, ignition etc.)
If the ammeter moves to discharge when the load is switched on, then the ammeter is wired correctly. If it moves to the charge side, then it is reading backwards and needs the ammeter wires switched from post to post to make it read correctly.
