Hi everyone,

Got a Chicago Coins "Juke Box" pinball machine at a yard sale this weekend. Works ok, added a new chime assy because the previous owner removed the original for some reason. So now that I got that working was wondering if anyone had any ideas why my backbox bulbs are blowing out. Put a DMM to it and it reads 40.6 volts, that's for most of the bulb sockets. The "tilt" works fine and registers around 6.2 V when lit. Only 6.2 V are being fed at the subpanel to bacbox connector (blue\white wire) and when I test any bulb socket in the backbox by touching the primary lead and using the subpanel ground instead of the backbox ground I get 6.2 V. Any reason why the backbox ground would increase the voltage by 33-34 volts ?

Thanks in advance !

Thanks !
