Hey everyone, I finally figured out the wiring and go to start the boat and no juice to the key. I hook up a volt meter to everything; switch panel, starter relay and have power. THen i hook up the meter to the coil and key nothing. So from there I put the meter on the circuit breaker and have juice everywhere but that little yellow and red wire. Any suggestions of what it is??? Should I try to jump straight to the starter???

Check this post (http://www.tmcowners.com/teamtalk/showpost.php?p=497184&postcount=16), its for a PCM, but it may help.

It does show a red and yellow wire.

I see the red/yellow wire goes thru the neutral safety switch.
Is boat in neutral?
Is switch ok?

with the key in the on position and not being in neutral would that cause the radio not to turn on too??

Tim's PCM schem' is much prettier, but this is what Engine Nut sent me for MC some time ago.

Yellow/red is the crank lead from the ignition switch. If the switch is mis-wired or something is disconnected at the switch, you'll never see voltage at the solenoid.
