Hello, my name is Greg. I am in the Navy so you think I would know more about boats than I do. I have a 1988 OMC Cobra 5.0. The trim will not work in either direction. Had the same problem last April. Took the switch apart, lubed it and bought a new battery (needed one anyway). It worked for the season although I would get a shock every now when I was wet and engaged the trim switch. Also, towards the end of the summer, sometimes I would engage the switch and it wouldn't work until I cranked the engine. Now it doesn't work at all, but both solenoids click when I engage the switch. The boat has been sitting for about 5 months while I've been out to sea.
This is what I have tried so far:
1. Charged battery. It is reading 12.6 volts
2. Cleaned all terminals (battery, solenoid in and out cables)
3. Jumped the wire directly to the motor. I hope I did this right. Unhooked the large blue wire and the large green wire from the solenoid and ran a wire from the positive battery post to the each of those wires at different times and nothing happened. I also unhooked the large red wire going into the solenoid and connected it directly to the large blue wire using electrical tape. Nothing happened.
4. Tested the amount of volts going to solenoids. Both were around 9 volts which made me suspicious about the switch. But...
5. Tested the about of volts going from solenoids and both were around 12.2 volts.
6. Rigged a separate switch going from battery to each of the solenoids. Nothing.
Would you have any advice? I was going to take the remote control handle apart to check the switch, but the multimeter showed 12 volts leaving the solenoid so I don't know if that will help. My next thought is to take the trim motor off and test it, but it is in a hard place to get to. Any advice on getting that thing off?
Thank you for any help you can give.
