    Turn signals work fine until I put the truck into reverse. Once I put it in reverse it blows the fuse. What gives. Thanks for any responses.

    Turning signals and reverse light switch share the same fuse - A short in the reverse light wiring could be the problem. If you are running additional reverse light you might want to check there first.

    Just one set of reverse lights. The originals. How do I find the short?

    I would start at the bulbs and work you way forward. If you have a trailer harness on the truck check that. THe tail light harness runs up the driver side frame rail. Just in front of the bumper it T and runs through the tail pan ( part where the hinges to the tail gate bolt too) to the passenger side. If the truck has ever been rear ended might be some wires damaged. The harness passes through a few holes in the tail pan. I would look to see if possibly the insulation has been worn off and it's grounding out.
