My car needed a jump start this morning and a friend came over and got it started. after we disconnected it we decided to check if the altarnator was still good. the cables got switch and neg went to pos and pos went to neg. How bad is it?
sorry guess It was confussin…. I didn’t pull the cables from the battery Itself i pulled off my jumper pack (which is a black and decker) after it started . then decided to check the altarnator . Not sure if i put the cables(to the jumper) on backwards. cause the second i put them on the car shut off and i took the cables off with out checking if they were on backward(neg to Pos) . but the car is fine i just had to rejump it.
