First, check to see if the arm is actually being moved by the motor. No, there's no reset needed. Next, try manually moving the arm by hand - note that there is a short delay in the readout so take that into consideration. If manually moving it works... see my post in that other thread you asked this question in. I still can't explain it.

But, one of the best things you can do is to forget about the trim gauge. Mine hasn't worked in 5 years. A gauge is just a very general guide - the best way to trim is by the seat of your pants and/or watching where the spray exits the side of the boat. No two sea conditions and load conditions are the same so the gauge, again, isn't always that useful.
