wiring is smoking on start up

[84cucv1ton]

bit of an update.. Cleaned all the grounds on the front of the truck and the flatbed. Clean all the wires on the terminal and all the grounds going to the motor. That braided little wire is very clean and still heating to the point it smokes.

Next idea is to go get a bigger table and make a new ground see if that does the trick. Thanks for the help guys

The problem is that one of your ground wires isn't conducting all the current that it should, so that little one in the back is carrying too much.

You don't need a BIGGER cable, you need a GOOD cable. Bigger won't hurt, but make sure you are solving the right problem. You've got a bad ground. You need to find where that bad ground is and fix it.

new day is here going to recheck everything..

Get a meter on those ground cables. Disconnect and check the resistance (ohms). A visual inspection isn't good enough, and good connections on each end don't mean the cable in between is good.

So what did you fix? Replace any wiring? Glad to hear you got it running.

redid all the ground.. forgot about the front one where you need to remove the grill and the one by the gas tank.. checked the ones i did put some electric grease down to stop corrosion.. then old welding cable from a intake bolt to the cab.. must have been pretty bad.. cranks over faster.. thanks agaon.. glad its running to

runs great. Still having a few wiring problems. Every time I had some good bumps in the road. A 20 amp fuse blows. I lose the running lights. Turn signals headlights break lights still work. Just no running lights.. Not too sure how to tackle this...
