Turbo timer killing the car

[gstjoker]

My battery is just some regular battery. I think it's Everstart brand? Don't know why but just remembered how there's always some corrosion coming from the positive end of the battery side. There's always some green/bluish powdery stuff that's surrounds the positive. I asked one of the guys at Autozone I trust and he says it's probably a bad ground or that it's really hot in the engine bay and that those powder stuff are just the battery's oil or whatever it is.
