My yoke mounted electric trim switch stopped working Saturday. I verified I have power to the switch from the on off switch on the panel. My avionics guy won't be able to look at it till next month. But he tasked me with doing some more trouble shooting on it. He wants me to ohm the wire harness at the servo to make sure it isn't bad before changing the switch. I have an Stec 30 w/alt hold. By the looks of it the trim servo is on the left and I'm guessing the unit on the right is the alt hold se
