thanks for your help. You can file this one under "stupid", i would love to blame the chinese for this one, but when i installed the new wiring harness in i did not have tail lights so i rolled the wire going to the rear of the truck up and tied it off under the truck. Once i got it ready to run i started it several times and let it run a few minutes.. the harness was against the exhaust pipe and that is where the problem occurred. The left turnsignal wire and the tail light wire insulation melted and the copper touched for about an inch. i would have found it a lot quicker had i started at the source on each wire it would have become obvisus where the problem was. thanks again for your help and encouragement. On to the next adventure.
