i need help again, lets start with the stupid thing. both pos. and neg. wires are black(not because of burning, just dont have a red one), i bought an optima red top and connected the wires, smoke came from the selenoid. now my amp light is on and meter reads in the red,stereo and aftermarket fog lights both are not working also,but the fuses for them aren't blown. two days later battery is dead. can anyone tell me what happens when you cross wires?
