On the bracket next to your trim pump are two solenoids. One has a blue wire it is the up solenoid. The other has a green wire and is the down solenoid.

Using a volt meter or a 12 volt test light put your tester on the large lug of the down solenoid with the green wire. Push in the trim switch and you should get voltage on the green wire. If not put the tester on the small green wire on the small terminal. and see if you get voltage when you press the down button. If you get voltage on the small green wire but not the large wire the solenoid is probably bad. If you get voltage on the large green wire but nothing happens, then the trim motor is probably bad. Usually it is the solenoid at fault.

Make sure all connections are clean and tight.
