Finally getting around to finishing this. Motor is back in and getting everything wired up.

Cant get the gauge to work. Its stuck up. Brown/white wire is connected to one side of the sendr Other side is grounded

On the gauge the needle stays up with key on or off. Jump the s terminal on the gauge to the ground terminal and gauge goes from pegged to full down. Turn keyy off or remove jumper wire and gauge goes back to full up

Any ideas?

When the position sensor fails the guage defaults to full up. Dumb question but you tried spinning the adjustment puck in full to the other end of the range? My Siearr units lasted about 3hours before I had to disconnect them and jump the wires together and fly blind again.

I set it in the middle position but it still pegs the gauage. Ill try moving it around and see if i can get anything. I have a feeling its a wiring issue. I did find a couple wires unhooked and re soldered/ shrink taped em. Previous owner did some wiring hacks that i am just now finding. Every other gauage seems to have power to it its just the dam trim gauge. Ive spent the past 2 nights chasing wiring. If it wasnt for this dam gauage i would have this thing fired up on the hose this morning.
