I towed a 32 ft tandem axle trailer for 10 straight days GVW was 24 K. Pickup performed great, I was really impressed. The trailer on the other hand was an electrical problem from the get go.

Now that I have the trailer disconnected, when I go to brake or put on my right turn signal there is a dong/beep sound that comes on each time. I figured it was just a sound that lets you know that you have a blown fuse. Well I checked the fuses that I thought it could be and they all look good. Does anyone here know the correct bank on the fuse box I need to be looking at?

 

Well I found the 15A fuse bank for the right blinker. The fuse was not burned up as I was expecting. So I pulled the fuse and checked that I had voltage coming to the fuse bank, and sure enough I had around 10 - 11 V. Can someone help me here I am sure this is pretty simple stuff, but can not find the problem. Thanks everyone.
