Trim Pump Issues Please Help

[JaSla74]

My trim pump was going out on my 87 Alpha Drive. It was clicking, but the motor was dying. Occasionally it would work, but sounded like a dying cat & finally killed over.

So, I ordered a new motor & installed it, but then it would not work from the switch. I referenced the manual and found that if you jump from the power lead to the small blue/white, or green/white wire on the solenoids, then the solenoid would need to be replaced

So, I replaced both solenoids, but it still will not work from the switch, nor will it jump on the smaller wires of the solenoid. I can jump the power lead to either the blue or green coming from the motor & it works fine.

I'm stumped. Please help.

The small blue and green wires coming from the switch are low amperage and just tell the solenoids when to work.
I would suspect a fuse is blown or the switch got fried.

Go to the Adults Only thread and find the manual for your engine and drive.

There is a very comprehensive troubleshooting guide here for trim systems.

Good luck.
