Tilt/Trim not working

[FishNovice101]

I have an early 90s 65hp Johnson outboard. This past weekend the tilt/trim did not work at all. There is a connector at the motor under the hood that runs the controls up to the throttle control and to the switch up in front of the boat. We unplugged that plug, and then the tilt/trim worked on the motor only. If we plug it back in, it keeps blowing fuses like there is a short somewhere.

Does anyone have any suggestions of where to start?

Thanks!!

Sounds like either a stuck relay or a short in the wiring for the other parts of the boat that control the tilt trim.

I had something similar a few years ago. In my case the wires that control the tilt had gotten cut at the pivot point where they enter the throttle control.

We were thinking a short somewhere, but it worked a month ago. Maybe mice. I'll be tearing into it tomorrow. I'll let you all know what I find. Thanks for the tips.

This is where I'd start.. if the wires are tied to tightly near the control box this is pretty typical.
