"I have a strange issue I hope
"I have a strange issue I hope you guys can help with. Boat is a '95 Four Winns Freedom 170 with OMC 4.3L Stern Drive
When I went to use my boat last weekend the starter re-engaged a second or two after the engine started. Turning the ignition key to the off position did nothing. The engine and starter stayed on. Pulling the emergency cutoff also did nothing. I was able to turn off the engine by removing the relay on the left side front of engine. This relay appears to be wired to the starter position of the ignition.
We have so far replaced the ignition switch, relay and starter with no positive results. Since the starter seems to re-engage a second or two after the engine starts I figured it must be somehow getting power to it again when the alternator engages.
To test this we removed the alternator belt and started the engine up. The engine started fine and the starter did not re-engage. We were also able to turn off the engine with the ignition key as expected.
Suspecting the alternator was having a problem we removed it and took it to an alternator shop which said there was a problem with the regulator. We had the unit rebuilt and re-installed it today only to have the same problem.
I don't have a service manual for this engine handy and am out of ideas at the moment. The alternator has more stuff wired to it than I expect to normally see on an alternator and am having a hard time understanding why the starter would re-engage when the alternator starts producing power.
Here is how my alternator is wired up. It is a Mando 55A with a total of 6 terminals on it.
Terminal E = Black Wire
Terminal B = Large gauge Orange Wire
Terminal S= Purple wire and red jumper that goes to the Exc Terminal
Termina Exc = Red wire which jumpers to Terminal S
Terminal L2 = Green Wire
Terminal P = small Purple wire
The wire from Terminal S has continuity to a purple wire on the starter solenoid.
If anyone can help I would appreciate the assistance."
