1984 115hp Evinrude wont shut off.

The engine wont shut off but runs great.  I have replaced the ignition key, I've traced the black w/yellow stripe wire from the key to the ignition box. I plugged and unplugged the wire at the ignition box but it did not change the condition. Also the wire is a ground. Is that correct? Or should it have voltage? Can any one help me? Thanks

The motor turns off when the keyswitch grounds out the black-yellow CDI wire to the black ground wire. If there is an open circuit anywhere in the black-yellow wire or inside the power pack, the motor will not shut off. Check the connector terminals carefully.

I cut the connector off at the CDI box on the black/yellow wire and put directly to ground with no results. Should I look into buying a new CDI box? Thanks

[ Edited ]

If by grounding out the black-yellow wire on each power pack at the same time and the motor continued to run, then one or both of the packs are faulty internally and would have to be replaced. There are isolation diodes inside the packs to keep one "kill wire" from affecting the other pack so if one or both packs have open diodes, then the motor will not shut off if it continues to run on the other 2 cylinders.

 

If you are only grounding one powerpack, the engine may continue to on the 2 cylinders that are operating on the opposite pack. Both packs have to be grounded at the black-yellow wire for the motor to quit.

Re: 1984 115hp Evinrude wont shut off.

I ran into more issues when you said I should have 2 CDI box. It only has one. For some reason it has two more coil wires that are caped off like someone got it from a V6. Is there some V4 models that only have one CDI bow? I do know that there is not any more wire harness coming out of the magneto area for more CDI box. The model # on the engine mount at the transom is E115TLCRD. Is there any other ID tags on the power head to see if they match. Thanks

Re: 1984 115hp Evinrude wont shut off.

The parts book shows that your model number engine has dual power packs. Your engine may be the result of someone's mixing and matching of other components to jury-rig an ignition system, especially since extra wires are taped off.

On that motor it was common to find the black/yellow wires from the Power Pack to be broken inside the connectors or the pins and sockets broken.   The black/yellow wires have to be grounded to shut the motor off.
