1994 Johnson 175 turns over with key switch off?

[kfraser65]

I pulled the motor to do a clean up / restoration of the boat. I reinstalled, and now when I turn on the battery switch, with the key off, it starts turning over? Bad key switch? Stuck solenoid? All of the wiring remained in place and nothing has really changed. Thanks in advance for any suggestions.

disconnect the control wires on the selenoid if it cures the problem then the selenoid in OK but is being energized look downstream.

first try to tap the key assembly to see if it releases the selenoid ... having reconnected the wires of course.
if it clears the problem===> bad key ..sticky contacts inside (replace the key

if not disconnect the key end .. control wire to the selenoid... if it clears the problem ===> really stuck contacts inside the key replace the key assembly

lastly if the key end wire is disconnected and problem persists look for a shorted control wire to a 12V source between the key and the selenoid

one diagram of a shows that control wire is tapped (branching) into a EMM type controller . In any event no 12v should be present in a continuous basis on the selenoid control wire

If you take battery cables off positive/negative terminals it resets the ECM. I would try that as well.

and....the problem was ??

Funny----I do not believe that a 1994 model has an ECM.

 

[Crosbyman]

going by pictures available of the wiring diagrams (around same years) but if no ECM that makes it simpler

update: possibly a C.D. unit not an ECM as you indicated the selenoid control wire splits to the selenoid and... the CD unit

getting the proper diagrams is tricky :-( basic trouble shooting remains but we may never know the answer....

Remove all wires from solenoid.

Check for continuity between battery and starter posts on solenoid. Should be open.

Check for continuity between control posts.

Check for 12v between (+) control wire to solenoid to ground. On/off should be controlled by key switch
