    My truck won\'t stop eating fuses

    Okay, I'm having a big problem with fuses.. specifically my "tail light/complementary" fuses. Every time it rains, this fuse always needs to be replaced. Now, all of my loose wires have been electrical taped and no water can get in. Yet, every time it rains, it ALWAYS goes out. I'm starting to get mad now, because I'm always waiting to get pulled over when I'm driving in the rain. Anyone have any ideas why it keeps shorting out?.. maybe the wrong # fuse (I have a 30 in it). Perhaps my diamond plate of red lights in the rear has been shorting it out? maybe water getting into something? The thing I don't understand is that it's always that one fuse. Help!

    After spending days disassembling the whole light system to find a similar problem, it turned out the former owner must have loved the trailer light connector, because he just cut it off and left the wires hanging, well last winter the salt got onto the wire and my lights and fuse box had a field day. I removed everything and replaced each piece one at a time making sure each had a good ground till I found the problem. And which, by the way I had found a broke wire to the rear window and put a splice connector on it , only to have it corrode all over again.
    Tape will not keep the water out....best thing I have found it underground splice taps the phone company uses or take a single wire splice, put the wire in and crimp it down, then fill in around the wire and the open end with RTV, now it will be corrosion and short proof. I now RTV all connectors just in case... If you need anymore help or ideas just ask....happy to help.
