Positive First. When installing a mower battery, always connect the positive cable first. The positive cable is red. It attaches to the battery terminal post marked with a plus sign, the letter P or the word POS. Attach the negative cable last. The negative cable is black.
Hook up the positive battery terminal first then the ground. Make sure you know wich cable is wich. The ground ( usually black on American cars, brown on European ) will lead â¦from the battery negative pole to the body of the car or be grounded on the engine probably near the alternator.
