I've been blowing fuses as fast as I can replace them for my hazards/tailights. I'm wondering if anyone knows of a common starting point to locate a short. The bulbs are all fine and I haven't changed any of the wiring in the truck. Any help would be appreciated. Thanks.

 

I had the same problem on my 84 150 and I tok my tail lights off and found a short.One of the wires was bare and shorting on the body.

 

I agree. It sounds like a short. Check wires where they are spliced, have connections, etc. Any place they could have exposed wire.
