Just picked up an imve today. Kicker/opto not cooperating. The opto light is on and the kicker works when I test it, however nothing happens when I place a ball at opto. Maybe if I roll a ball into it I will get a kickback 1 out of 20 tries. Usually it doesn't register it at all. I've cleaned optos and made sure all connections are secure at the opto board. Not sure if it could be a bad board or a connection I am missing.
