91-92 150hp Force Mag Issue

[littledragon]

Hello!

I have the 1991-92 model 150hp US Marine Force engine. This engine does not have the info plate located near the carbs, but the engine stamp and little alloy plate is on the (electric mounting array side, where the tach, temp, mag array) and that plate reads JAN 98.

Used motor, installed, roasted the voltage regulator by how I had the wires hooked up. I confirmed after another 3 hours research, while I wait for a factory manual, that I have trouble with only 2 wires. MAG white and MAG blue.

The engine wiring diagram from the book shows "ENG STOP" and "BAT CHARGE. "The "engine stop" post runs to the opposite side of the engine to the electrical cluster. The "battery charge" post runs towards the coil so to speak, where the starter, battery, and red wires are.

1 mag wire goes to engine kill, 1 mag wire goes to battery charge, correct?

On the side of your engine where the solenoid and the electrical bus bar is located.....look up towards the top of the engine. 2 wires come off the stator and connect to the rectifier/regulator. One wire comes off that and goes to the battery + connection at the bus bar. Those two wires from the stator....one forks off into another wire...that is your tachometer wire. The ENG STOP you refer to is the kill switch wire. It goes up and over the engine, under the flywheel, and appears on the other side ...behind the cluster of ignition components usually....where usually it is mounted onto a small bus where the wire(s) from your ignition kill circuit are mated to it.
If you don't know where to put the wire from the rectifier/regulator, i.e. BAT CHARGE description, you can run it to the solenoid on the hot side. Verify it has 12 volts all the time and you're set.

You really should have a vertical bus bar on the side of the engine. If I recall correctly, the 3rd wire terminal down is usually the kill circuit.
