1994 volvo penta 7.4 starting diagram

[llewis01]

I have a 1994 albemarle 265 with a 7.4 gm motor. I have problems with it starting. I have replace the ignition twice with new ones and replace the starter. Sometimes it will start when keep turning the ignition on and off about a does times. It will start every time when you jump the wire at the switch by jumping the hotwire to the solenoid. So I don't now if the switch is wired wrong and that's why I need a diagram to trace wires.

You have a start assist relay that is most likely the issue
Follow the Yellow/Red wire from the starter to the relay

Your key energizes the relay, and the relay energizes the starter solenoid
