Electrical wiring has always confused me. Now my 383 crate motor has a small starter on it with only 2 terminals on the solenoid. This is not working for me when there were 4 wires running to the old starter?
Don't any of these "whizbang" starters come with instructions? I see this question quite often.
Your starter harness has four wires (not counting the battery cable); a red main power feed wire and a black ammeter sense wire, both of which have large ring terminals and go on the big battery cable stud, a purple solenoid energizing ("start") wire with a small ring terminal that went on the inboard "S" terminal, and a black/pink coil bypass wire with a small ring terminal that went on the outboard "R" terminal.
With the 2-terminal starter the arrangement is the same, except you connect the black/pink coil bypass wire to the small terminal the purple "start" wire connects to.
If you leave the purple wire off, the starter won't work - that's the circuit from the "start" position of the ignition switch that energizes the starter.
