Re: OMC remote controls with the big red plug…

[johnyrude200]

well I think I figured out what the issue was. I ran through the process step by step of tracing continuity through the ground circuit, and what the problem was, is that the control box side of the wiring harnass has a different configuration of connectors.

So the black and black/yellow leads on the motor side, which the key should provide continuity for (closed circuit) when in the OFF position, doesn’t have a connector in one of the holes which the motor-side plug connects too. Therefore, no way to close that circuit in the OFF position and ground out the ignition system, killing off the motor.

I didn’t realize there is even much of a difference between these control boxes in the first place.

The box I am using is off of a newer motor (probably mid 80’s). After looking at either harness (either motor or control box end), it appears that the motor end is much simpler than the control box. These plugs appear to be molded and not modifiable, unless you drill out one of the holes to put the pin in where it needs to be.

Looking even further between some wiring schematics from a ’79 service manual, and an ’88 service booklet, these harnesses are totally different in terms of plug configuration. I’ve seen some motors pass through here where previous mechanics just spliced butt connectors and reconfigured things, abandoning the original big red/black plugs. Looks like I may have to do that to retrofit this control box to this older motor.
