blown fuse

veedub87 · #1 10-30-2002, 03:08 PM

The 15 amp fuse (in the fuse box under the hood) for the reverse lights, the day time running lights, and the cruise control keeps blowing. I haven't looked for anything yet because I don't know what to look for. Can anybody help me out?
My truck is a 1996 Ford F150 XL 302 4x4 Automatic E4OD currently equipped with a 7'6" Boss standard duty plow.

You say it has the snow plow kit...does it have the lights with it? If so you might check the connection from them or check all wires involved with those functions. Look for a chaffed wire.

Hope this helps.

could also try a higher amp fuse.

If you wired anything else into that circuit when you installed the plow, that's your problem. A higher amp fuse is required.

Take care,

I diden't see any chaffed wires, and the plow was installed when I bought the truck. I did try a 20 amp fuse but that blew too. I diden't want to try any higher because I diden't know if there was a problem if it would mess it up any further. Thanks for all your help.

You don't want to go with a bigger fuse because wiring isn't designed for it. How long does it take for the fuse to blow once you replace it? If it blows almost right away then you have a dead short somewhere. Otherwise you have a resistance problem caused by some severe corrosion. What you need to do is inspect all the wiring for those circuits and make sure there are no chaffed or broken wires. Does the fuse blow when the running lights are on? Or only when you shift into reverse? That can help you narrow down the problem to one area. The tool guys sell a thing called a short finder that works pretty good if you can find one for sale. otherwise you just have to do a visual inspection and maybe even get a ohm meter and check the resistance of all the wires in the circuit.

Have fun, electrical problems are great
