I currently do not have the key hooked up on an omc cobra 5.0 and would like to start it up to test the engine/outdrive. How do I hard wire jumper the starter? thanks.
Jump a positive jumper wire from the positive battery terminal over to the SMALL slave solenoid terminal that has the small yellow/red wire attached to it. This is the "primary" side of the solenoid which should activate the solenoid and connect the two larger terminals together to supply voltage to the starter.
I'm sorry, but if you don't know what a coil is, then you really shouldn't be hot wiring and jumping anything.
