Which Post Do You Remove First On A Battery. There are two primary reasons you may need to remove your car battery. I have a GM car that used the side post battery and cables.
If you can just connect the positive red alligator clamp to the positive terminal and the negative black alligator clamp from the charger to a metal ground on the car or the negative battery post and plug the OPTIMA charger in to an outlet it will eventually turn on automatically and do the rest. Read and follow the Safety and Handling information on this website before you begin. I have a battery that has both the side and top post.
The cpu will automatically reset once the negative battery post is reattached and the engine fuel pressure builds back up to its normal.
First remove all jewelry when working with tools even something as simple as a box wrench. The size of the socket may vary by vehicle American cars will usually need a ½ 516 or 38 wrench while common sizes for imports are 10 and 12 mm. Second always remove the battery. Next lower the battery onto the battery tray with the terminals in the right position and clamp it into place.
