I have power to the 50a circuit breaker on top of the motor, power to the starter, and I can control the starter at the helm. (no key, the boat has a start button and an "ignition off" button) I also have 12v power to the 10a top ECU breaker, mounted on the motor, but I have no power to the two 10a breakers mounted on the engine for the fuel pump and TBI/ECU. There is a relay that provides power to these breakers through a purple "trigger" or control wire. The relay has 12v battery power through the red, but no power from the trigger when the "port ignition" circuit breaker in the cabin is turned on. Starboard motor works fine.
I traced my electrical issue to the 9 pin male connector. (the side of the connector that comes from the helm back to the motor) I have absolutely no power from the helm back to the 9 pin connector. (no power to the fat #2 "battery" post, no power to the coil, no power to the starter pin) The engine alarms are not receiving power as well.
I bypassed the "engine off" button, and ran the fat red wire from the ignition circuit breaker right to the purple wires that first go to the gauges, then go to the 9 pin. I have 12v at the fat red wire, and have 12v at each of the three purple wires, but still nothing at the 9 pin.
Any ideas about what I should do next?
Boat is a 1996 Trojan 390 Express, made by Carver, to the extent that it matters.
