Just installed a Pinball Pro subwoofer kit, and upon firing the machine back up I'm getting the errors listed below. I checked the fuses with a multimeter and they are fine.

Looking for Ideas here on what could be wrong? Perhaps something came loose when I lifed the playfield? UGH!! lol.

pinrepair.com has a whole lot if information in the 'game reset's and 'opto switches' sections

this error means all of your optos are disconnected or they get no 12v

could be a fuse, bridge, connector
or the connectors going to the optos or maybe an opto board under the playfield
 
The 109 fuse blew, just replace it and all of that will go away

I think its a 3amp fuse, but mot sure ......just happened to me in my Junkyard
 
this may be stupid, but make sure the back of the new backbox speakers don't touch anything on the board.

i do my own speaker upgrades, and i have had a few that were damm close to touching the board...did 1 woofer install that wouldn't let me close the playfield 100% either...lol. little modding had to be done.
