I have a '85 Rinker V190 with a 3.8L v6 4v OMC. The engine runs great, however turning the ignition key to the off position does not stop the engine. I have to pull the coil wire to stop it. I tried disconnecting all 3 wires to the ignition switch and it still continues to run. When the engine is not running, the switch seems to work fine (dashboard lights go on/off with key turns). Ignition switch starts engine fine. Do I just have a bad switch to replace or is it something else? |

Dave, i had a boat that did the same thing, would start fine but would not shut off with the switch. Happened all of a sudden. Ended up being a bad diode in the alternator. Went to an auto electric shop and they put an inline diode i believe between the alt. and the switch to prevent the backflow of current.Everything was fine. Check with a local autoelectric shop and they should be able to help |

Time for an alternator checkout. The excitation lead is keeping the ignition 'hot'. |
