A buddy dropped off his 1997 4.3 mercruiser boat.
I'm a jet guy, what do I know?
Starts but runs only in start mode.
Power on purple wire from switch is ok to engine connector.
No power on purple wire at coil.
Jumper fixes it, but what is between harness connector and coil (all purple)?
Not a resistor on this new a system is there ????
Some safety system? From oil, temp, fuel sensor?
As you might guess I have no diagram and don't want to rip into it>
