I am new to this site and want to say hi to all reading this. I have a 2000 4R Limited with a factory towing package. I recently bought a used 6x12 U.S. Cargo enclosed trailer. When I connect the trailer lights they initially work but after a few minutes the 4R tail light fuse blows and all trailer lights go off. The trailer has a lot of lights: a row across the top front, a row across the top rear, front and rear side marker lights, front and rear lights on each fender, 4 tail/turn/brake lights, and 2 interior lights. Initially I thought I had a short but now I think maybe the trailer is simply pulling too much power for the 10 amp fuse to handle. As I mentioned, the fuse does not blow immediately; it takes a few minutes. However, if I connect the lights and then turn on the interior lights the fuse will blow immediately. Out of curiosity, I replaced the 10 amp fuse with a 15 amp fuse, connected the lights and turned on the interior lights. The 15 amp fuse did not blow. The fuse box shows the tail light fuse to be 10 amp. What are the potential problems if I use a 15 amp fuse instead? Is there another solution? Does anyone have any thoughts or suggestions? Help will be much appreciated.
