Got an old piece of vintage iron here that has a 12V alternator conversion on it. I "think" it's probably an early GM alternator, the only ID on it appears to be "Delco-Remy" from what I can see of it, some of it is hidden. It has two side-by-side male tab terminals recessed into the case (marked R and F) and it also has a threaded ground post coming out of the case. It has an external regulator box mounted away from the alternator. This regulator has two coils inside, one is probably the cutout relay tower and the other has a double point setup, I am guessing this controls voltage or amperage. The regulator box has four tabs coming out of the bottom, one is marked F and the remaining ones are marked 2, 3, and 4. The 4th one is used in a circuit through an electric oil pressure switch unit mounted near the oil lines on the oil filter assembly, I assume this is used to prevent battery discharge when the tractor engine is shut down. This tractor has a magneto ignition system so none of this affets the ignition system. All the above mentioned terminals are hooked up so something/somewhere, nothing is left unhooked (so I will assume that whoever wired this thing knew what he was doing). Sound OK so far? Can anyone guess as to what era of GM vehicles this setup came from? Now to my question, everything seems to work good, as a matter of fact it seems to work too good. It pins the amp meter right to the end at +20 amps and the battery voltage reads about 17-18 volts across it's terminals when the tractor is running. Can anyone tell me what's wrong here (assuming something is wrong). Any siggestions as to how to remedy the situation. Is that second tower in the regulator box controlling voltage or amperage? Thanks for the help.
