Hi Steve,
I have been looking at the 100-B manual and there is not a cabinet wiring diagram,
I have looked at a CD100 cabinet and can see that there is a small connector for the small lamps around the Animation window, listed in manual 7-2 under door lighting is the flouescent and the 11 watt incanescent (these must be 110/120volt) but also liisted is 14 volts incandecent lamps.
I would check to see if you are getting 14 volts at this small connector and trace it back in the jukebox, it looks as if it comes down into the amplifier compartment.
I hope this helps.
Regards
Alan
