Trim motor electrical trouble

[Billd232]

Mercruiser 4.3 LXH gen+. Trim motor for the stern drive won't run. The solenoid clicks when start button is depressed. Battery measures 12.5V. I measure 11.5V on the downstream side of the solenoid supplying the motor. I removed the motor and connected directly to the battery, and it runs. Is the 11.5 volts not enough to run the motor? Where might the voltage loss be? Is there another potential cause I am missing? Thanks.

If you hear the solenoid clicking but the motor does not operate, but the motor will operate if you jump the 2 large studs then solenoid is defective.or there is corrosion in the connections http://www.boatfix.com/merc/Servmanl/6/6A5R3.PDF

Thanks BT Doctur. Will disassemble and clean all connections first and see if that does it.

No Title

If you feel cheap, you can open up the relay and fix it. I did. I'm cheap. It worked.

Disassembled and cleaned all connections. Motor now runs down!..but not up. Must be a bad "up" solenoid. Think I'll buy one to get it running, then take the old one apart and try to fix it for a spare. Thanks.

Just an update. Replaced the upper solenoid and all is working great now. Thanks.
