08 Silverado 3500 6.6 Duramax 4x4 drw banks six gun tuner with speedbrake and airdog 2 lift pump. So I had left my truck in accesary mode by not turning the key of all the way( accidentally) when I arrived to a job ( bfe field welding) so when it came time to leave low voltage,no crank no start. Can you guess where I'm I'm heading? That's right DC welder generator 50 amps, then + to+ & -to - . The wipers take off on warp speed, the lights flashing, truck started up though. The low beams no longer work. When I got home parked it. Tried to jump it in the morning and got nothing at all. Where do I start. Not to many people on YouTube have made this mistake or will make a video that acknowledges the bright idea. I assume it will be expensive.
how much voltage did your welder stuff into your truck? Sounds like it fried some stuff.
I would start with the fusebox and see what kind of carnage there is.
