problem started with click no go issue. found bottom center wire on f/r switch burt off.. replaced switch with new board .. now i have no click nor will it move. I have no idea what I'm missing as in control power because the pack has 38 volts. One positive is i do have a back up alarm. i know this is simple stuff for you guys please give me the next step to test ..

Thanks so much
