I have a 1957 3100 with a 1960 235 and floor starter. At some point this truck was either originally 12v or someone converted it, I have no clue. The truck runs but I have no lights at all but I do get power to the instruments.
Tracking down the terrible rewiring someone has done before me I have fixed a ton of stuff but I'm confused on one thing. The 20 GA Violet wire running from the starter to the ignition switch and connecting at the Start tab on the switch is not connected at the starter. This wire, I believe, is the only way power can get to the switch.
I have two starters one is the one that came with the truck, probably not original and another one I picked up at the salvage yard. The one that came with the truck has a little mounting screw on the side of the actuator. The actuator being where the battery connects to the starter and the little Black wire runs from the starter to the ammeter. The one that was picked up at a salvage yard does not have this extra mounting screw and is currently installed on the truck.
The question is, how does power get to the ignition switch if not through the Violet wire and where should I connect the end of this Violet wire to on the starter? I'm hesitant because on the wiring diagram it says Resistor (by pass) in the mounting location of the wire on the starter, which is what I'm trying to identify, and therefore do not want to incorrectly connect it and screw something up down stream.
