Your starter is going out!!!!
:werd: And running anything aftermarket that is melting shit, doesn't help the electrical system, either.with the truck being a 2000, it is probably time for a new batt for the 2nd time. first one prob didn't make it past 03, rt? now this is another 3-4 years after that.
that would explain it...delco batts are shit. pure and simple.not sure what # battery its on, but i replaced it last winter with a AC Delco replacement battery.
