Bad trim pump or bad solenoids
 
If I touch the solenoids with 12v they just click. If I touch the trim pump with 12v the trim pump will spin. Bad pump or bad solenoids??

It could be the 110 amp fuse as well. You have to check the connections on the Solenoid. Does your trim work at all (up/down)?

Best to start on basics,check grounds to pumps this is one of the biggest culprits.Next test to see if you have voltage to the solenoid packs.

If you put power to either the blue or green wire on the large post on the solenoid and the pump runs, then the pump is fine. That also means that it has a good ground.
Put a volt meter on the small blue and small green wires on the solenoid and have someone push the trim button. The small blue wire will have +12V when you push the trim up and the small green has +12V when the switch is pushed down. The other small wire on the solenoid is a ground. Make sure you have a good connection there as well.
If the solenoid is just clicking, then you are getting power to it. The internal contacts are brass and the solenoids are not sealed, so the brass contacts corrode and won't make a good connection.
Hope this helps.

I had one with shot brushes. Guess the previous owner liked to trim mostly with one tab because the other side and the drive pumps were fine. It would just click, and sometimes catch and go, mostly not. $3 later from McMaster, I put new brushes in it and it works like a champ.

Very well said!

Sounds like Youngs Perfomance is on the right track, I would also check the 3 prong connector at the pump. Have seen them work loose or something land on the wire harness pulling the plug just enough to make a bad connection, there should be a clamp on that connector, My thoughts have seen it more than once.

Just replace the solenoids and your problems will go away. Ediie is correct in checking the system out.

So I am having a similar problem, my trim would only go down but not up. I switched the two solenoids and now I hear clicking only when I try to trim down but it won't move. Does this mean the solenoid is bad or the pump?

Internal contacts of the solenoid need cleaned. Likely corroded. Did mine last year. Problem solved.
