Trim Sender/Limit Mercruiser

[blazer]

Hello, I have a 95 Bayliner Capri 4.3LX. The trim switch on the controller only goes down. I have to use my trailer switch to trim up. I replaced the trim sender and limit switch on the outdrive, as well as the trim switch on the controller. No luck! Any suggestions as to what may be the problem would be very much appreciated!

Might not be adjusted correctly
Use a ohm meter and check continuity with drive down across the 2 leads from the limit

Ok

Ok

So I have continuity on each wire. There is no power however coming from the wires deriving at the controller switch at the point they plug into the trim sender wires. I press the trim switch up, no dc power. Should be 12 volts?

This is the wiring
When Reg trim is pressed up, it comes down the Purple/White wire. Thru the limit and to the Blue/White to raise drive

Trailer, goes straight to Blue/White and not thru limit

Does the ignition key need to be in accessory?
Could it be the 110v circuit breaker?

No
No
It's all 12v

The power to trim motor doesn’t go through the 50 amp breaker on the 12 v system ( normally mounted on engine on mercruisers)

Yes, 50 amp circuit breaker, thanks. Well I'm fairly certain it's all connected correctly. Could it be a fuse?

I had a similar issue, where it wouldn't go down. Ended up a wire had broken in the throttle handle. It was in the last spot I thought it would be after checking everything else, and I wasn't even going to check there. You could test continuity from the trim up switch at the handle, backwards?

Thank you Alldodge, Scott06 and MarcelSydney. I watched a YouTube vid called "How to install, adjust trim/limit sender switches." In the vid he shows on one of the plastic gears there is a raised line that lines up with the units plastic housing. I received no instructions with this part so, duh, thanks to you all who helped me hunt down the issue. Now I have to go have some fun!
