Quoted from EvanDickson:
Did you double check all the connections per the instructions?
Also, is the opto calibrated? Mine would never stay calibrated until I glued the dial after setting it (probably not good advice).
Look at rhe board near the trunk opto, with a little dial that can be turned with a small Phillips screwdriver, turn it one way until the red light comes on, and then turn it the other way until the red light *just barely* turns off.
Yeah, i double checked based on the directions and compared vs pictures of other installs on this thread. The trunk is calibrated and was working perfect before the install.
