You should have small diameter low amps wires that go I to the relay these will be to engage the relay. Try connecting the wires to a stand alone twelve volt battery.
POWER TILT TRIM Temporary Down Lockup.
Power tilt and trim just clicks. There are two. If one is bad both will not work. You will see a two wire plug with a green and blue wire.
Unhook this plug and remove the two wires. Put one on pos and the other on a neg. The motor should run.
Reverse it and it should run the other way. Pressed the up button and wahlahnothing. The motor was working but the engine wouldnt tilt or trim.
So I tried to bleed out some air which requires it to be raised and lowered. So I performed this by hand a few times and pumped in some more fluid until it reached the fill screw. Definately sounds electrical.
Before you buy a new battery try swapping to one of your t-motor batteries if problem persists go from there. If the trim motor clicks then something is locked up. Have someone hit the switch while you hold your ear next to it.
If the relay is clicking then you either have a bad trim relay or a bad trim motor. There are 2 different ways to tell which of the 2 it is. The first way is to check the voltage out of the trim relay on the large blue and green wires when you hit trim down.
Trim motor lost power I hear the click when pressing the trim buttons though Check your battery connections make sure the terminals are scrupulously clean and also wire-brush the pos and neg cable lugs. Make sure the wingnutsbolts are tight too. A sure sign youve got an issue at the terminals is a hot connection.
The trim system is relatively simple once you understand how it works. There are 3 parts to the system you have the trim buttons the trim relay and the trim motor itself. The clicking you hear is coming from the relay which means the switching portion of the system the buttons is working okay.
My tilttrim just clicks when I use the switch. Worked fine last week. The solenoids have been checked and pass.
The engine is in the down position and wont go up. Ive read several forums and my manual which suggests it might be air and that there might be a manual relief screw on the starboard side to get the engine up manually. If you hear a slight clicking noise while pressing the tilt switch then you have power from the control switch to the solenoid or relay.
The next step is to check the operation of the power tilt and trim motor itself. All tilttrim systems use a 12-volt DC reversing-type motor that has one green wire and one blue power wire. I told him was to disconnect the motor pan tilt switch and go from there.
If if were the relay 150 gone bad then the trim would not be working at all. The other switch on the throttle 55 could be shorted out but not likely. I found that there were a total of FOUR switches that control the trim on this boat.
The cure is to loosen one of the large tiltsteering nuts 12 turn then with a 24 and a large hammer force the swivel bracket sideways slightly. Force grease into the grease fittings on the front of the swivel bracket. That should do it.
POWER TILT TRIM Temporary Down Lockup. There should be a hole in the transom bracket usually the port side next to the TT with a large flat head screw thats slightly recessed. Unscrewing that screw 14-12 turn will release the pump hydraulic pressure in the tilt.
The engine will go down with. IF IT JUST CLICKS then jump across the large red and large blue wires. If the tilt and trim motor works fine but the engine wont raise or lower slips down when in the raised position or wont stay trimmed chances are that the problem is with the hydraulic pump or valve body assembly.
If it doesnt work on either youve either got a bum connection to your trim motor or the trim motor is stickingfailing. The fact that you pulled up and down and it startedstopped working might lead to it being a stuck ram on your trim motor. Check to make sure both click.
And yes even though it clicks it could still be shot. As far as the wires. You should have small diameter low amps wires that go I to the relay these will be to engage the relay.
Then larger diameter wires high amps to run. Disconnect your battery or pull your PTT fuse. Take the green and blue wires loose from the PTT relays noting that the blue wire should be in the top relay.
Get a couple of wires with alligator clips on both ends. Try connecting the wires to a stand alone twelve volt battery. If the Motor runs you may have a problem with a solenoid or lack of voltage coming from the power Trim and Tilt switch to the solenoid.
If your power Trim Tilt Motor wont run after this procedure it is time to replace it. Some replacement Power Trim Tilt motors will come with a new wiring harness and relay kit to convert your old three wire power Trim and Tilt Motor to a new more. Power trim adjusts the outboards angle for different water conditions improving the boats.
Acceleration speed and ride quality. Power tilt raises and lowers the outboard for trailering mooring beaching and launching. The power trim and tilt unit is located.
When I went to start it back up the starter only clicks and does not engage the flywheel. My tilt trim also does not work now but I can hear the motor trying sounds weak. I charged up the batteries when I got home and now my gpssonar vhf bilge pumpstereoetc.
The relay would click but no action. Sometimes the motor would move sometimes not. The outboard is in great shape overall and was used only in fresh water until this spring.
Judging by the dried fresh water growth on the lower unit and the tool marks on the power trim manual release Id say the motor had the trim unit problem for some time. Testing wiring and bypassing SPDT power trim tilt relay harness. Does not apply to older SPST relaysDoes the electric trim and tilt pump motor not move.
First disconnect the power Trim and Tilt Motor. Using a jumper wire apply 12 volts directly to the blue wire if your engine or drive unit is in the down position. It should raise up at this time.
If it is in the up position apply power to the green wire reversing the Motor and lowering the unit. If the Motor runs you may have a problem with. My F225 TXRC Power Tilt and Trim is having issues in the down direction.
Before I took it apart the power tilt would work normally in the down direction and then the power trim would work normally in the down direction for about 12 of the stroke and then the PT motor would make the sound like it was at the end of its stroke. The OD trim limit switch will only send voltage to the trimtilt switch in the upward toggle position if the OD limit switch is below the adjusted trim limit that keeps the OD being out of the water. To test the limit switch circuit lower the OD to the down position and slowly raise it with the trim toggle up until it stops.
I have experienced the same problem a few times with a 1992 Mercury 75 HP tiller. It is most likely the relay for the up stroke just because they click does not mean they work. They are the same part number for both up and down I would suggest you get one and change it out.
One time I replaced the relay and it would still not work.
