Tilt Trim Question?

My tilt / trim stopped working. I checked the fluid, and its still full. The relays were both clicking, so I replaced them, but it didnt change anything. Right after I got the new relays on, I was trying the switch and it was just clicking, and then for a second the motor started to make a noise and then nothing again. I have checked all wiring and anything else I can think of. So, at this point im thinking its the motor. Any opinions? Also, I am at my next dilemma, do I order one off the web, or do I try to get it rebuilt? Can I pull it off without pulling the outboard to get to it? I can see 3 bolts in each corner of the motor housing, but cant see the 4th? is there a 4th? Any advise would be appreciated.

Sorry, I meant to put this in the mechanical section. Can a moderator please move it?

A local auto electric shop should be able to rebuild the motor. As to how many bolts.... what model is it?

The motor is a 1993 Mercury 150 xr6, I dont know any other model numbers orthe than the fact that is the square tilt/ trim motor with 3 wires.

I just had mine fixed at a local armature shop for $30. Alot cheaper than buying new.

Forgot the most important rule of all of this. Check your battery. Check your battery. Check your battery!

You must have a fully charged battery in good shape to run these tests. Relays don't like low voltage at all! They have contactors in them that get pulled together by electromagnets that are powered by the battery. If they are pulled with a weak battery, you can get arcing and carbon build up on the contactors and the relay will become bad quickly, even though it works fine. Charge your battery and check its voltage. You should see about the same voltage through out all your tests except when the motor actually runs. It may drop a bit then, but otherwise, it should be very close. If its not, check and clean all connections and load test the battery.

Blue should be your up, green wire is down, and black is battery negative. Connecting black to the battery negative and the blue to the battery positive will run the motor to tilt/trim up.

Black to ground and green to positive will tilt/trim down. You can test directly to the battery. If you get nothing, or only one direction you have a battery issue. If you get movement in both directions then you have a switch or relay problem.

These can range from failed or miswired to weak corroded connections. Start at the battery and test.

Yours is a reversing motor I believe and doesn't use the reversing relays, unless you have a black wire run to the case of the motor as opposed to coming out of it with the other two wires.

You can test the switch with nothing more than a continuity tester. You can test the relays with a test light or VOM meter. Relay 2 is the up relay and relay two is the down relay.

Relays normally have three bigger wires coming out of them and one smaller. One of the bigger ones runs to the tilt/trim motor. The other two are connected to + and - on the battery.

Went press the tilt up at the helm, the wire to the motor on relay 2 should show battery voltage. If not, the relay is bad or miswired.

When you press the tilt down at the helm, the the wire to the motor on relay 1 should show battery voltage.

Also, check for power coming into the relay from the switch. In other words, the small wire each relay. You should see battery voltage on each wire according to switch movement.

If your switch and relays check out, and the wiring checks out, and the motor checks out.. then you have a hydraulic/mechanical issue, but since the motor ain't running, I think its electrical.

GL...

Oh, and I think your motor only uses three bolts.
