Theres a pair of wires that come off the switch. Connect your multimeter to the terminals with the meter set to OHMS. Move the arm and watch the meter.
Thats pretty much all the trim gauge is is an ohm meter. I have the boat at home getting ready for DS. The gauge is pegged.
I have a good ground and 105 volts at the power wire going to gauge. How do I test the gauge. Shouldnt it have gone to down position when I removed the power wire from gauge.

You would loosen the screw on the plastic piece and adjust it by rotating it on the shaft. That piece when the motor tilted moved an arm on the switch which in turn sent the signal to your gauge. Trim Limit Switch Testing 1.

Im on vacation at Lake of the Ozarks and yesterday while fishing my helm trim indicator gauge started bouncing around. Motor is secure – just the gauge. The SmartCraft digital trim indicator is doing the same thing.
Its just the gauges going whacky – the motor itself is trimming up and down just fine. So buy a manual. Starboard side on the gimbal ring.
Take it off and fiddle with it. If you can get it to get the gauge to go up and down Id bet it was simply out of adjustment. It may still go to heck once I get it in the water but right now it sure seems to work when it didnt before.
Installed new trim sender and trim sensor on the lower unit. Connected the trim sender wires from the lower unit to the brownwhite and black. A boats trim gauge monitors the position of the drive or outboard.
Make sure its accurately adjusted. Grab a level and place it against the underside of the anti-cavitation plate on the drive or outboard motor. Have someone at the helm adjust the trim until the instrument reads level and note the position on the indicator.
Bump the trim button up and youll notice the bow rise the steering will feel lighter and boat speed will increase. Notice that spot where spray breaks off the hull moves aft as you trim up. Drag is significantly reduced and efficiency is enhanced.
But if the engine is in the down position energize the blue wire which should raise it. If the engine is in the raised position connect the jumper to the green wire to lower it. And if the motor fails to operate with power applied directly to.
If the TRIM gauge and the sender are matched to each other the calibration adjustment generally is limited to a mechanical change in position of the sender relative to the outboard motor. If the TRIM gauge and the sender are not matched to each other you might see the effect as a change in the dial calibration. If there ever was a setup that was almost designed to fail its that trim gauge.
Fixing that thing will probably be dependent on how badly you want and need it in practical terms. You will probably find the problem lies in the sending unit disk which is a PITA to change out if its a stern drive Mercruiser. Because it is a complete wire set.
Got 25 hrs on it and got the boat to top out at 46mph. Here is my question about the trim gauge. When we got into the shallow water and trim the motor up the gauge read all the way up but the motor was still very deep in the water.
I did a test when the motor gets to where the fast trim trailer trim starts is when the gauge read all the way up. First visually inspect the trim sender on the bracket. It could be stuck or broken.
If you can follow the wires into the boat there should be a disconnect - take them apart and check for resistance to change in accordance to someone manually moving the sender.
