1979 SRV300 Sportbridge - port engine won't crank

[evilsizer]

I need help, where can I get a complete wiring diagram?

Ignition is operational but no power at the starter solenoid.
50 amp breaker has power on both sides - this is good
I can jump the starter - engine starts

Is there an amplifier or another switch somewhere?

I have a wiring diagram for the boat but mine is a little older. Should be the same as far as your connections to the harness. You will need a wiring diagram for the motor harness as well. It's in the appropriate Mercury service manual. I have that too. Send me the motor serial number and I can look it up. I assume it is a MIE255 with points for the ignition and not thunderbolt HIE?

Thanks, I will find the moter searial number this weekend.
Our engine are equiped with electronic distributors. I don't know if that will make a difference in the wiring diagram.

Port engine won't crank - No power to the starter solenoid was due to a faulty Neutral Safety Switch.
Sorry Captian Ron, hired a tech to solve this problem.
