I had the fuse break on a Joker 200 light, but I don't know what could cause a surge of electricity (no lightning storm at the time). If it matters, it could have been on the same line as a coffee maker/toaster/microwave. Please help me out. Thanks!
A surge is not going to blow a fuse IN a ballast. A fuse will blow when there is too much current flowing - which might be a loose wire touching ground or two wires shorting. If the fuse is in the fuse box then something else being on the circuit might blow the fuse.
The main component in the ballast is a large inductor, and if a turn gets shorted, it will draw high current. Suspect the ballast. Also, with a coffee maker and a microwave, the total current could be too high for the circuit breaker.
