Short/Open-circuit(s) Blowing Fuses

I noticed today that when I pressed on the brake before I started the truck (or even put the key in the ignition), I could hear the Stop/Hazard fuse blow. [img]/wwwthreads_images/icons/mad.gif[/img] Then, when I drove and put the turn signal on, I could hear the Turn/Backup fuse blow. [img]/wwwthreads_images/icons/mad.gif[/img]

Is there a causal relationship here? [img]/wwwthreads_images/icons/tongue.gif[/img] I know I can find the answer on my own, but I am asking in case someone else has had this problem and what they found out ("shortcut"). [img]/wwwthreads_images/icons/laugh.gif[/img] Thanks in advance.

I found out that the turn signal fuse only blows when the right side flashes. [img]/wwwthreads_images/icons/smile.gif[/img] I have to buy more fuses now.

Re: Short/Open-circuit(s) Blowing Fuses

It honestly just sounds like you have a wire grounding out and shorting the circuit somewhere. The tranny was a good idea, it might grounded out. But I would check under the dash to make sure that all wires aren't rubbing on grounded areas (nearest to the fuse block) and go from there!

Hope you find it without much trouble!

Problem Solved

I found it, [img]/wwwthreads_images/icons/cool.gif[/img] finally. It was the wire running from the right side tail light to the trailer harness, thus blowing the brake light fuse and the turn signal fuse (when using the right turn signal). [img]/wwwthreads_images/icons/cool.gif[/img]
