Yamaha 90HP 2 Stroke (1997 TLRV)
In preparation for boating attempted to raise motor by tilt/trim switch. Motor sounded but could not lift engine. Was able to lift the engine by hand while pressing ‘up’ switch and safety locked in place.(also used the manual screw on side) The ‘down’ command resulted in no movement but ‘clicking’ at the relay area. Checked the hydraulic fluid which appeared full and tried to add Yamaha fluid but it was too full to take anymore. Did not help the problem.
Researched Youtube and checked the relays with a 12 volt light tester. The red terminal showed positive. So did the blue and green terminals. This suggested a bad tilt/trim motor. Replaced with a DB Electric model which had good reviews. After installation- no difference.
Went back to investigating the relays. Connected the blue grommet to the red power and no response. Same with green. Tried connecting green (down) to blue terminal- no response.
More online research came across a comment that the relay terminals may show voltage but may not have enough amps. ???? Should the relay unit be changed?
(also ran across a reference to a little switch behind the main swivel that can get stuck. Found nothing like that but did find a light weight plastic ‘sleeve’ that easily spins around by touch. I do not think this is involved.
