When I run a lot of electric stuff in my truck at the same time (radio, wipers, lights, heat , Etc) when I shut the truck off is has a problem starting back up like the battery is dead. It's not because it's new. I have noticed there are 2 positive cables going into the battery. The red plastic is melted and seems to heat up. When I play with the cable it starts right back up. Has anyone ever heard of this? Thanks for your help.

sounds like the positive cable is earthing out somewhere. trace it back, probably goes to the starter solenoid. check the tightness of all of the terminals and check the main terminal is clean and has a good connection.

Replace the melted cable with a larger diameter if possible. Possible cause for melting is a long hard start, pulling that many amps through a cable that isn't big enough for the load will heat the inside of the cable almost like the filament in a light bulb, or a car cigarette lighter. Once over heated just once raises the resistance in the cable making it harder for current to travel through it lowering the voltage.

Anytime electricity meets resistance, heat is the result. It could be just a matter of a corroded connection to the battery causing excessive resistance and thus the melting. Definitely replace the melted cable, check for dead shorts and clean all connections.

Reason for the plastic to be melted is due to loose connection. Replace both positive battery cables and make sure all connections are tight. Also check alternator output.

Replace the cable with a larger one. Sounds like the cable connection is corroded, causing a voltage drop, which causes higher current draw thus melting the cable cover.

probably all of them had 4L60E transmissions that are truthfully digital 700R4s. they are only too vulnerable for that super of a automobile. finally end up a three/4 ton suburban with a 6.5 diesel or a 454. A 1500 suburban with a 6.5 diesel will artwork too. No 454s in the 1500s. All 454s and all 6.5 diesels have 4L80E automatics. Its truthfully a TH400 with an overdrive. I truthfully have a ninety six suburban 1500 with a 6.5 diesel and it has 251,000 miles on its unique 4L80E transmission. Very sturdy trans.

replace the battery terminal(s) and run a larger positive and negative cables. Alot of people end up doing this and on the chevys its called the "NBS big 3 upgrade" (search "big 3 upgrade" on any search engine).

You might have to still replace the battery just because of having everything running at once. try and pump the gas when your starting up your car. I suggest you it here strip or replace the melted red plastic.

Take the 2 cables apart and clean between them then reinstall them.
this set up gets corrosion between the cables that can cause this problem
