Hi guys, I recently swapped a Johnson with an Evenrude engine. After finally getting it to run, when I turn the ignition key to shut it off the motor keeps running to the point that I have to pull the spark plugs cable to shut it off. What could be the problem? Thank you. |

Either the stop-circuit int he Power-pack does not get grounded, or the PP itself is defective.
Pull the black/yellow lead from the power=pack, start the engine and ground the black/yellow. Engine should stop.
If engine stops, take an Ohm-meter, attach one pin to ground and the other to the black/yellow in the engine wiring harness. In stop position -0 Ohm = short circuit. Of not, keep on measuring all the way to ign key. |

I had some time today and went and work on it. Well I checked the black-yellow wire, I make sure that it was grounded and also check it for continuity. I trace it all the way pass the wire harness plug. I opened the the power-pack apart pulled the wire out. put one pin on the black ground wire and the other on the terminal where the black/yellow wire was then i would turn the ignition key on and off and i was getting a reading. Then i turn it on, turn it off but still it keep running. |

Once again:
Pull the black/yellow cable out of the connector from power pack.
Start the engine.
Put the black/yellow FROM power pack to ground.
Does the engine stop? |

Hey,,, I went back to it and I had check that the black-yellow cable was grounded. I also check that the ignition switch is working. I guess that I wasn't giving it enough time so that it would shutoff by it self. I took it for a ride and when I turned the switch off it did stop but it took a while. I turn it on again and adjusted the spark thing. And now it's working fine. Thank you Morten Your help is greatly appreciated. |

If it does not shut off immediately (cut ignition), it is an indication that You have a faulting ground or connectivity issue somewhere in the circuit. It may be a 'dirty' ground connection, it may be one of the pins in a connector only hanging to one strand in the cable. Ohm test is done at a very low amperage and may read out ok, but amperage may not be enough. |

I just went through this. One of my connections on the starter switch had worked its way loose. It was the shut off one. Put it back on and perfect shotoff. |
