I was working on trying to get a single non-working opto going by installing a new opto board. Now am having trouble with almost every opto in the game including the hour optos in the clock. I haven't been able to figure this out. The 12v is getting to the opto board. I am able to trigger all the non working optos in the switch edges test by pulling the connectors off of J1 & J4 of the opto board (goes to the receiving optos) and jumpering 12v to each pin. The transmitting LED pins at J2 & J3 are also reading 12v. Putting the old board back in makes no difference. Reseating the and wiggling the connectors does nothing either. I can't find any way to clear up the clock optos. I've tried reseating the connectors to the clock too. What could be causing this? I'm stumped.
