Trim gauge lease help
« on: April 15, 2017, 10:27:46 PM »
After this long wet winter I went striper fishing and notice my trim gauge doesn't work.  The boat will still trim up and down. Has any one ever troubleshoot the motor trim gauge?

 They are easy to trouble shoot.

The old type trim senders are just variable resistors (rheostat) a wiper arm that runs on a wire resistor.

Check for 12v behind your gauge if it is present there go to the connector at the sender. If you have 12v at both locations  then disconnect  the connector and install a ohm meter...trim the engine to see if your resistance changes.

The new types of senders are sealed and not serviceable, you can open and clean the old type.
