My neighbor’s trim doesn’t work from the throttle. I am pretty sure the trim switch is bad but I am far from an expert. We took the throttle off but the two screws in the back are frozen so we can’t get to the switch itself. I can see where the three wires go into a crimp and three wires from the handle also go into the connector. We have voltage in that connector. Would you agree if you have power in that connector then the switch is probably bad? Also, is it possible to buy just the handle and a trim switch? Thanks.
