I apparently blew a couple of gi circuits on my back of star wars and trying to figure what to trouble shoot. all fuses apparently are working. Used different bulbs. Maybe my next issue is part of the same issue or 2 separate issues. However half my back box is out and the other lights are very dim. Once again fuses seem to be ok. What could be a cause of this. I'm guess a short of some type, but what are some common issues could this be. This is not the first time I've come across this, so I better learn how to deal with this. At least if I can narrow it down a bit could be helpful. Thanks
