    It was the heat shield hitting the touching the solenoid b+ battery cable. When I went under the truck the heat shield sparked then I disconnected the negative and just pulled it off. There was no screw holding it in place. Took pictures. Thank you guys for all of your help.

    I found the one behind the driver wheel and cleaned it. Is this what you are talking about? So far. I changed the negative ground and both grounds behind the driver and passenger wheels.

    Where are the ground points?

    Hey. I changed my negative ground cable, cleaned the grounds behind both wheels. My problems seemed to get worse. What else did you do and can you post your videos that helped your issue. This is killing me. Thanks for your help.

    Thanks for the reply. I found the one behind the drivers side wheel. It was covered in grime. Cleaned it off and will test it on my way to work. I hope that helps. New battery, new negative battery cable.. I guess I'll do the ground strap and look for the one in the cab.

    They won't find anything. I've been to 2 places. One shop specialize in electronics the other was the dealer. Well, $300 later still no solution. I did find there was a crimp in the negative cable connected to the frame. It worked for 2 days then got even worse after. This morning my headlight...
