Trim guage indicating opposite

[Noie]

Hi,
My trim guage was not indicating properly so I loosened the two adjusting screws on the sender and rotated the unit. When I rotated it cw simulating trim down, guage showed it as trimming up. ccw did the opposite. I reversed the wires at the unit but it did the same thing. The only way I could get it to correctly reflect what was actually happening was to install it on the port side where the trim limit switch is! Works properly there! Have any thoughts on this?

My thoughts are that the 'port' and 'starboard' are usually marked on the sender units . . . I can never remember which one goes where. but they may have been on the wrong sides of the outdrive as you indicated.

Trim "Limit" goes on port and trim "Sender" goes on stbd. Something doesn't sound right..... Is your gauge on the dash wired correctly? Black wire to "G" teminal, purple wire to the "I" terminal and the brown / white wire to "S" terminal?

Well I checked what you said and wires are different colours but seem to be correct? Did notice that port puck has T.L. on it as it should but stbd puck has P.. Could that mean 'Port' as it should be on the port side? Are these both port pucks?

Sender for the gauge will be a variable resistance and should be on sbd. The trim limit is a make / break switch and should be on port. Have no idea what the "P" stands for, unless the switches are an off brand which makes the whole thing any man's guess if they aren't just like the Merc stuff

Senders are as you described (resistance and switch). Stern is an SE106 from Stendrive Engineering. May run this past them.
Thanks for your input.
