Wiring on Generator
I have three wires that go to the generator. An 8 or 10 gauge dark brown one, a 12 gauge dark blue, and a ground wire. Which goes to what post. They were unhooked by a buddy when I removed the instrument cluster last weekend. There is also a resistor with a ground wire that goes on it also. He doesn't exactly remember what went where, and I have no clue since I wasn't watching. I do not want to hook these up wrong. Thanks

Like this - the 14-ga. brown goes to the armature terminal, the 20-ga. blue goes to the field terminal. The ground (shielded) attaches to the case with the capacitor; use the right screw - if it's too long, you'll ground the field windings (not good).

53-62 Generator wiring is ultra simple.
Just remember the SAME wire goes between the field terminal on the gen (F stamped into the case) to the field terminal on the regulator and the armature terminal on the gen (A stamped into the case) goes to the arm terminal on the regulator. A heavier gauge wire (usually brown) is used for the armature terminals and a lighter gauge wire (usually blue or may look purple) is used for the field connection. The reason for the heavy wire (braided stainless) is to provide a solid ground for the regulator (NOT the generator) because the regulator is mounted to a fiberglass fender panel (no ground path there!). The braided wire needs to be connected to the regulator case, NOT one of the mounting screws for the regulator (because the regulator mounting screws go through rubber bushings on the regulator frame, again, no ground path). If the regulator case does not have a screw on the side, then connect the braded wire to one of the cover attaching screws.
