    I converted my six hella 500's this last weekend and i noticed that the inline fuse from the battery now gets so hot i cant touch it. I used 55w hid kit and have all six lights on three different switches. what should i do?

    Did you wire in relays? check all your wires sounds like you have a short, bad ground, or used to small of wire. Did you run one power wire or 3?

    What amp fuse did you use? Most fuses will blow before they get that hot.

    What gauge wiring did you use? Each pair of 55W lights will draw 10 amps or more. So each pair of lights should be wired with a minimum of 12 gauge wire.

    If you have all 6 55W lights on 1 wire you are running 330W which is 27 amps! Thats a lot. You will need at least a 10 gauge wire or larger.

    Remember, the longer the wire the larger gauge. For example, if you are running 27 amps for more than 10 feet you need 8 gauge wire.

    wow lol i currently have 18 gauge wire from battery to my relay, with a 15 amp fuse. I bought some heavyduty in line fuses with 15 amp fuses and some new 14 guage wire, to rewire between the relay and the battery. Going to the lights i have 16 guage wire should i re do that too? it doesn't get hot at all just the wire between the batt and relay does...

    So all 6 lights are powered from one 18 gauge wire and 1 15 amp fuse? Thats not good, the wire will melt if the fuse does not blow.

    You should run a separate relay for every 2 55W lights. And use 12 gauge wire and a 15 amp relay for every 2 lights.

    If you want to run 1 wire from the battery to the relays I would use a 8 gauge wire and a 30 amp fuse on that one wire.

    I cant believe the fuse isnt blowing. But you have 3 relays I would start by running the larger power wire to each relay make sure you fuse holder/wire is larger as well. Going from 12 ga wire to 18 ga fuse holder isnt gunna do you much. So start there and see if that solves your problem but i have a feeling you mite have to run larger wire to the lights as well.
