## How do I know if my car battery is negative or positive ground?

Find the negative terminal on your car battery and if it is attached to body of vehicle then it is negative ground. The battery should have a – for negative on the negative post(usually a black cable going to it) & a + for positive on the positive post(usually a red cable).
