Starter Solenoid Wiring Issue

Hey all!

I've been having issues with the starter solenoid on my boat for a while now. I think when I rebuilt the engine I mixed up some wires to the solenoid. Right now there is a draw on the batteries. It seems like simple wiring, but I am mentally challenged when it comes to wiring.

I have found a few wiring diagrams, but none seem to be what I am looking for. As far as I can tell, relative to the solenoid there is battery in, starter out, ignition switch in, alternator in, neutral switch, and one mystery wire I haven't traced.

Can anyone provide a simple picture or diagram of how this should be wired?

Thanks ahead of time!!!!

Depends what the wires go to. Main terminal in usually has the fusible links. Second main is power out. S (left small wire) goes to start and the "I" terminal gets a boost of power when cranking only. Usually to an ignition system that runs a resistor to boost spark while cranking.
