Re: 1994 Force 150hp won't shut off
Check the terminal board inside the cowl and locate the black/yellow wire that connects with 3 white/grn wires. These wh/grn wires are the shutdown wires for all three modules when connected to ground. Get a jumper wire connect one end to ground and touch the terminal board with the three wires and the engine should shut down. If it does, it could be the black/yellow wire is disconnected somewhere or severed someplace. You need to do a continuity check on it to make sure it is still connecting.
