Power trim issues.......

I have a couple issues with my power trim. First, the trim motor just mysteriously quit on me. I used the power trim one weekend to raise and lower the outdrive for some maintenance and it was just fine. I went to use it the next weekend to raise the outdrive to do some trailer wiring and the trim pump is just plain dead. I checked all the wiring and didn't see anything that had come loose or corroded. Is there some way to jump across the solenoids to check and see if its the motor or the solenoids? Second issue, my trim rams seem to be leaking down over time. Is it possible to pressure test them like you would an outdrive to see if its actually the rams or possibly seals in the pump? I would like to try to isolate my problem before I start throwing money at it replacing unnessessary parts. Any help will be greatly appreciated. Thank you and sorry for the novel!

Use a test light at trim pump 12 volt its the motor. No volts and it is supply or solenoid

Here is a link to the OEM service manual. have a look at section 1C for detailes troubleshooting of the trim system.

You could have good power at the trim pump, and it still not work. Could be the wiring, fuse, or the connector going to the helm control. Might as well follow the charts and save yourself a lot of trouble.

Thank you both for the timely responses and the wealth of knowledge. Any thoughts on pressure testing the trim rams?

Look in that manual I gave you the link to. It has ALL that information in it.
