Another question I have. I need to hook up my SID 5-bulb marquee back up. Just to save me time looking around for the manual, do they hook to 12V on a standard jamma power supply?
 
Maybe I missed a step here? I plugged my wires up to 12V and had none lit up? Are they all blown or was I supposed to run one of the wires to ground?

I realize I look like an idiot for asking this. Thanks for the help.
 
If you cabinet doesn't have any hackery going on.....the 12 volt line is tapped off the transformer. This is unregulated 12 volts AC.

120 volts goes into the transformer from the line cord.....a 12 volt output winding leaves the transformer......one wire goes through a fuse.....and both wires end up at a connector....and travel on to the bulb sockets....where they're daisy-chained to each socket.

Check your fuse.....follow the AC with a meter.
