I have 12v at the C2 connector to the tilt motor and the relay clicks when I press the trim down switch. All works fine trimming up. Manual says to service motor if it doesn't work with power at the C2 connector, but is that the problem if it works trimming up? Could it be a hydrallic issue keeping the motor from trimming down? Trying to take boat out today and this happened! Been working fine up to now.
