Starter Solenoid (Starter Relay)

On the bulkhead....

The white braided cable is the high current lead from the solenoid to the starter. The smaller wires control it.

One side from solenoid to starter, other side to ground? I have one little wire. Does that go to the "I" or the "S" side?

No. One side goes to the starter and the other side is the battery positive (+12 volts) terminal.

One of the large terminals will be marked "BAT". Connect the battery positive cable to this terminal. Connect the other large terminal to the starter.

One of the two small terminals will be marked "S". Connect the small wire to this terminal.

The other small terminal, marked "I", is unused.

Here's a picture, worth 1000 words.

The wire connected to the "S" terminal is the wire that activates the relay.

The wire connected to the "I" terminal connects directly to the coil positive terminal, bypassing any ballast resistance in the ignition circuit. It is intended to only provide power (100% battery power) to the coil during starting. Ignitions which operate full time on 100% battery voltage, such as Duraspark I or EDIS, do not require this connection.
