What is the main cause of a volt gauge showing a negative reading when the car is running?

please clarify your question before reversing any wires. . what do you mean 'reads negative' ?? is this a stock meter, reading from 0 up to whatever positive, or does it have a 0 in the middle and one side neg 12 and the other side pos 12??
If you reverse the leads inappropriately, you'll at best peg the needle and that can bend it. . the terminals on the rear of the meter should be labeled This is when a picture is worth a thousand words. . OR are you talking about a VOM hand held mult-meter. . If yes, then reverse the leads. . red to positive |
