Battery drained out, we got a jump and made it home (about 7-10 miles) if acceleration was kept charging battery. Next day barely went five miles and it shut off completely. I bought three alternators and two batteries. There is a drain still even when it's turned on and revved up. Not charging battery or battery drain so intense it can't charge fast enough. TPMS sensor light on none of TPMS sensors or module is showing nearly the mhz it's supposed to. Checked all ground wiring and wiring harness for damage or frays, nothing. Checked fuse box, cleaned it and replaced all fuses, still didn't fix it. Checked all lights on and in the vehicle to make sure they weren't staying on, they weren't. Nothing stays on after the vehicle is turned off. Battery drains only when turned on and run. Battery charged fine (sometimes cables get hot if from one vehicle to trucks battery). The amp wiring has been removed. New terminals put on. Radio unplugged and removed. Friend brought and used an Autel reader showed everything working fine accept alternator not sending charge to battery. It didn't show any cause for it all sensors are tightly plugged and no bad wiring. All spark plugs are in good standing. The belt is in perfect condition. Spindles are in perfect condition and evenly placed on. I don't know what else it could be. Why won't it charge the battery?
