merc trim and tilt

To check the motor with a three wire Trim and Tilt bypass the solenoid/relay.

blue wire to Positive = Trim UP
green Wire to Positve = Trim Down
Black Wire = Ground (duh!)

Make sure you have a good ground.

I have several sets of these relays/solenoids and I have three wire motors too. The 3 wire motors are a PIA to replace . . . after you do one you'll wish you had the Old Style Single Ram Piston with External Trim and Tilt Pump (Still used on the racing motors).

big so the old single ram system that ive got in the garage is still worth holding on to?

actually that is the system that is on the boat. one really big ram and a remote mount pump and tank. my motor is a 1980 didnt have time to test it today since i was setting tile all day in my master bath remodel.

I have two external pumps too. Same test for the external pump . . . since it has the three wire motor. Could be solenoid/relay . . . or motor. Putting current directly to the motor will test you right away.

well i went out there and tapped it with a hammer a few times and it started to work . i stopped going down and it will not restart while being tapped on. i will perform a voltage test when the rain stops.

sorry about the delay it is the solenoids. one of the big lug terminals is loose in the housing and makes contact temporally . i need to replace the solenoids, are these the same ones that ford trucks use or are the different since this is a marine enviroment?

i think they are the same ones that are used on your starter motor. no i dont think you can use the ones from a ford truck. might want to get the marine ones for this application. just my opinion.
