tilt trim suddenly stopped working- troubleshooting?

[boatdude100]

3L GL Volvo SX drive. Was working fine however, thumb switch has a history of not activating perfectly every time one time out of 20 I have to push it twice. however...

I hear clicks when I move the switch both up and down. No motor activation .
I'd jump it if I could find clear instructions on exactly what wires to jump please?

How should I proceed? Thanks so much folks!

Just to add..
Boat is a 2007 Stingray
I can't even find the motor itself so I don't know what wires lead from it. I did however see a 2 wire connector with a blue and green heavy gage wire tied to the trim sensor wire so I assume that is it? How do I jump it? One to pos one to neg, then reverse?

I saw one post with what seemed to be a similar boat saying pump/trim motor was outside the hull? If so, is it now inaccessible because the motor is stuck down??

And fuses.. Is the trim motor is either a large orange 40 amp fuse or a large yellow 20 amp fuse. Maybe??

Please help- How should I proceed? Thanks so much!

check the main power harness on the motor/relays. the control voltage for the switch and the relay coils comes from the helm. the power its switching comes from the starter.

Thanks Scott, I did a visual , tightness and corrosion inspection and all seems good with the harness and other wires you mentioned. Not sure how to check it further.

I found info on jumping pump/motor and harness with blue and green wire. I will try blue to neg and green to pos and as I understand it (with luck) it will go down....

BTW, I never have checked trim oil level... could this be a cause?

 

[Scott Danforth]

do you have a 3-wire motor or a 2-wire motor. that determines how you jump them.

if you hear the pump run, however it doesnt sound right, that would be oil level.

Thanks Scott more excellent pointers. 2 wire motor, jumped as described in my last post. Small spark at battery when touching wire but nothing. No sound, just a welling feeling of defeat in my heart.

Also, tested for continuity and found open circuit going to motor at connection
Showed +12 v when using switch on throttle to trim up and -12 down

From this info, what is to be concluded please?

Motors are about $75 on Amazon

 

[boatdude100]

So having jumped directly positive and neg to blue and green wires and getting no sound, this means the motor is shot?

Q1)Is it true that for a SX-A trim system, the motor is not available seperatly-without buying the whole pricey assembly? Coule not find a motor for SX-A on Amazon or i-boats

Q2) Is it possible to have these motors rebuilt?

 

[boatdude100]

Did I fry the trim motor by jumping it wrong on Sx-A??
2 wire motor
What I did: from battery: - to green + to blue on connector going to trim motor on transom.
Is this the correct procedure or did I just cost myself a lot of money as it shows "open circuit"
Please help!

2 wire motors. Connect one to +, one to + and motor spins. Flip the wires and it spins opposite

Putting + on blue would make it go up

However sounds like your motor is dead or stuck

Is no sparks, going to assume dirty or worn brushes
