Hi everyone. So here’s where I’m at.

Starting at the back. I have a spare, fully charged, battery in the boat with me. Ground the battery to the engine and supply positive to the lower BLUE WIRE WITH WHITE STRIPE and the trim goes up like brand new. Supply the same positive wire to the upper GREEN WIRE WITH WHITE STRIPE and the trim goes down like brand new. Motor works perfectly.

My next step is to test the entire system a little more…’upstream’. So now I’m looking to test the wires heading to the stern of the boat from up at or near the dash / throttle assembly. I found a connector which is located just before you get under the dash coming from the throttle assembly (which also has the trim buttons on it). The wires I see are one WHITE WIRE WITH BLUE STRIPE, WHITE WIRE WITH A GREEN STRIPE, and I believe the third was WHITE WITH A RED STRIPE.

So I’ve heard that supplying power to each one of these independently and having my spare battery grounded out to the engine may indeed get the trim to move up and down. This is my question…does this sound correct?

Back story: I heard that the trim would sometimes work when the boat was in gear but not in neutral. Sounds like a broken wire at the “flex point / pivot point” of the throttle assembly!! That’s what I’m hoping for.

Any pictures, wiring diagrams, advice, tips, past stories would be greatly appreciated.

Thanks,

Do you have an OMC control? if so I know for sure that there is a good possiblilty that it's a broken wire inside...I was getting a pretty good shock whenever I trimmed down and was touching the metal destroyer steering wheel of my boat...asked my mechanic about it and he said the down wire was probably grounding out on the control handle...I took off the OMC trim piece and you can see were the wires come out and there was a break in the insulation...I fixed this with some liquid electrical tape and then used some trim adhesive to glue the grommet that is supposed to protect the wires (it had pulled out of the control handle) back into the handle. My mechanic said they re-wire these controls often, sometimes it's necessay to replace the trim switch on the control....
