I have a Johnson 2001 90hp motor that I use in salt water. <br />The trim guage quit working.<br />Can anyone give me some tips to get this guage working again? Thanks
I always wonder why anyone would need one of these. <br /><br />Anyway its either a bad gage, bad sending unit, or a wire fault somewhere. The sending unit is a simple potentiometer check it with an ohm meter. The readings and a troubleshooting procedure are in the shop manual.
To check the gauge, run a small jumper fron the "S" (sensor) terminal to ground. If the gauge is good, that will peg the needle every time you touch ground.
