Trim Motor Failure?

Hey folks -- Running into an issue with the trim, and since I've never had any issues wanted to bounce it across y'all to see if I diagnosed it correctly.

 

1999 Yamaha 90 outboard, "C" IIRC although I don't think that matters.  If it does matter, it's whatever came on the 90SS Skeeter. 

But I'm 99% positive it's C.

 

Trim works up fine, but only clicks when you attempt to go down.  Trim motor does not "try" to run, just a click from the solenoid.

I checked voltage at the solenoid.  Blue across black, 12v when I go up. 

Green across black, 12v when I go down.

I traced (and shook while attempting down trim) the wiring and found no cuts, or shorts.

 

At this point, I have to suspect I either have a bad connection at the motor itself, or the motor is failing.  I would have expected it to fail both directions, however.  I did not expect the motor to work in one direction and have no reaction in the other.  That makes me think maybe I have a bad connection somewhere internally.  (Unless there are two separate motors in there?  Doesn't make sense, but IDK.)

 

Any thoughts?  Am I going down the wrong rabbit hole, or is it time to pull things apart and dig deeper?

 

 

 

I just saw this and see how you solved the problem I have for down.  My bow switch works fine so I know it has to be the control toggle.  I have a Yamaha 6XO Control and am trying to figure out how to get inside the control arm to the toggle trim switch,  I assume the whole arm has to come off the control unit.  Any tips you can pass on will be appreciated.
