    I think i got a blown fuse. I looked at the diagram provided by the manual but it doesnt list it. Back tail light/ back up (reverse) light keeps blowing out. Ive put in new bulbs and it will work fine but another one will blow out from somewhere else in the tail lamp area and when i replace the bulb, another bulb will blow out from somewhere else and so forth. Im guessing a blue 15a? Anyway i want to make sure. Do i need to dissconnect the battery before replacing?

    If a fuse was blown, none of them would work, sounds more like a short.

    The right answer is to disconnect the battery when doing electrical work.

    Fuses break circuit paths, stopping current flow, which means the equipment on that won't work. Markstang is probably right that there is a ground on that circuit. You may want to install a lower amperage fuse to protect those bulbs.

    Thanks for responding guys.. Unfortunately ive been having another issue. Now my engine is starting to smell like burnt electrical components. It seems like its coming from the alternator, its making this whine sound when i drive around. Almost like a supercharger sound but a silent version of it, if you will. The weird thing is that no check engine light will appear. Should i replace the alternator? And do you think it has anything to do with my weird lighting occurrances?
