my poa isnt working, it doesnt work in test mode and optos dont trigger. I removed motor and hooked power to it and it spins and gear looks nice, so i assume motor is good, i ordered the great lakes opto board. Theres another board (see pic)under pf that motor hooks directly to, i think its called brige driver board in manual, a-15946. I dont see the red light on, should it be? where to order that board if its bad? how do i test it? thanks, bear with me im new to fixing pins.
