Re: [OMC-Boats] Another Wiring Question

Lee,

Thanks for the additional info.  That made complete sense and indeed resolved the problem.  The voltage meter turns on and off with the key and I get plenty of charge reading to be completely satisfied that it's working properly.  I'm feeling pretty good about it all now.

It's tentatively supposed to be a decent weekend, especially Sunday at 80 degrees so I hope to get the boat out for a finally test run.  It will be so nice if she runs, and stays running at full speed for the afternoon! 

Thanks for the help on that one!  I had it close but with your extra boost, I think I've got it all resolved now.

Subject: [OMC-Boats] Another Wiring Question

I've pretty much resolved the wiring issues but I do have a question regarding the connections involving my new voltmeter.

I'm using the 1968 Wiring diagram you provided earlier as it most closely represents the overall setup on my boat including the open wire connector found at the rear of the engine (none of the other diagrams I've seen show that).  I'm also using the 73 vintage V8 diagram you provided as well as a 1970 color diagram Ethan (70' Explorer) provided.

Regarding the connector at the rear of the motor, this is where the three heavy gauge power wires connect from the engine harness to the forward boat harness.  Because of the split vintage of the two harness's, the wires change colors at the connector to match the forward wiring harness:
   Rear--->Forward
   Brown=Orange  (alternator)
   Green=Red (battery)
   Black=Black (ground)

I found a Clymer's wiring diagram that had a sections that suggested when replacing an Ammeter with a Voltmeter only, to connect the orange and the red wires together on the input side of the voltmeter.  I've done that.  The voltmeter now has two oranges, one from the rear and one to the fuse bank, and the red direct from the battery via the connector strip.

I now have charging but.....now the voltmeter stays powered up at all time which represents a minor drain.  The voltmeter should only be powered when the key is on.  It's here I'm drawing a blank on how to accomplish that.  If I disconnect the red, then there is no power at the front.

I'm missing something here and drawing a blank on the resolution.  Can you suggest anything?
