I have several tractors with Delco 1 and 3 wire alts on them. Question on the 3 wires- I finally found a nice red "idiot" light that will fit where I want one to go. This is the light that I understand runs from the #1 terminal, (closest to BATT stud on alt), to a switched stud on the ignition switch. My question is simple and rather dumb I suppose- 2 spades on the light, do they both get wired in the line (series?) or does one go in the line and one to a ground? For kicks I held one spade on the batt term of the alt while it was running and touched the #1 line to the other spade and it lit up, but didn't start charging, but did start charging when I held the wire to the stud directly. Maybe someone has addressed this but I missed it. It's all pretty much magic to me...
