Ok.. so a few weeks ago there was a post about 12v conversions. I asked a few questions since when I converted My massey Harris to a 12v, it would charge, but if it sat the battery was always dead after 3 or 4 days.
I wired it as it said.. 3 wire delco
Battery terminal of alt to + side of ammeter (as the generator was)
Terminal 2 jumped to batt terminal of alternator
Terminal 1 to coil side of ign switch (with a small "idiot light" in line (one side of light to ground, other side to the wire)
Once started, the light DOES NOT go out as it was said it would (and yes, I revved it up.. ammeter shows a charge) If I turn the key off, the tractor continues to run, until I unhook the #1 terminal. If I leave it unhooked, the alternator does not excite. It said to use either a light, a resistor, or a diode, and that I didn't need to use any combination.. just any one would work fine
What have I done wrong?? I don't consider myself dumb about this sort of thing.. and I followed the directions, so why is it not working like it should?
