I would need a bit more information before trying to accurately diagnose. Though if the lights are shutting off on the ZSR and come back on when you reset the power it would be likely that you have an intermittent short / ground somewhere in your low voltage wiring. The fuse is designed to protect the transformer and board against this kind of problem.
I would suggest contacting us directly with any further questions.
Sorry to hear about your troubles, Patrick.
