Cathy, sounds like the hanging light has developed a short somehow and that is what blew your fuse, are you certain you have a blown fuse and not just a tripped circuit breaker. Most modern homes use circui breakers to protect the house wiring versus fuses that when blown must be replaced. The two adjacent flourescent lights are powered off the same power feed that comes off the blown fuse which is why they are not working either. everything else in the kitchen you mentioned are powered by a differenct circuit and fuse or breaker. Please confirm that it was a fuse that blew and not a circuit breaker that tripped. If its a breaker try resetting it and try your lights again. Otherwise, if it was a blown fuse you need to locate and eliminate the short before replacing the fuse. hanging lights are no more likely to cause a short in the wiring if they are wired and hung properly. with the fuse out of the panel and the light switches all off, remove the cover plate on the ceiling for the hanging fixture and carefully inspect the wiring for signs of bare wire touching metal or try and see if the black wire is somehow contacting the white wire conductor or the bare copper shock protection ground wire--which could be why the fuse blew. now carefully inspect the wiring running down the chain for signs of a short having occurred. If nothing obvious then your short may still be there but is escaping visual inspection. Your choice then would be to tighten the wire nuts up good such that no bare wiring is exposed for the white and black insulated wires...and If the electrical box in the ceiling is metal then try to make sure the white and black wires when pushed back into the box do not contact the sides of the box just incase that was where the short existed. then replace your blown fuse with a good one and see if the short is gone by turning on the switches one at a time . If your fuse blows again repeat the trouble shooting steps above until the short is located. possibly the short could be down at the light switch for the hanging light as well so maybe it would be wise to check the switch wiring for shorts too before replacing the fuse. Hope this helps some... post back with more data or results from your troubleshooting.. LJ
