Re: Trim/Tilt Problem
Waytam, The trim gauge is easy to test. There should be a power, ground, and signal wire connection on the backside of the gauge. You need a ground to the gauge and 12 volts power. The "S" (signal) connection is the wire which comes from the trim sending unit on the outdrive. Drop the "S" wire off the gauge and connect a 10 ohm or so resistor between the ground and "S" connections, the gauge should indicate a trim down indication. Change the resistor to 40 ohms and it should indicate around mid trim. Change the resistor to around 160 ohms and it should indicate a full up indication. Using a variable resistor of suitable resistance would work as well and the gauge should move smoothly as the resistance is varied. Personally, the trim gauge and sending unit will not be the cause of your problem with the stereo.
