How Do You Install A Dual Battery Isolator On A Race Car?
Race cars require the maximum level of power from their battery at all times. The high energy ignition systems along with the numerous electric fans and pumps that are used to cool braking components and rear end lubricants put a tremendous load on a charging system. Couple all of that energy draw with the harsh environment that a race car’s charging system operates in and it is easy to understand how a charging system failure could take a car out of a race. To combat this threat, most race cars carry a second complete battery system on board despite the extra weight. Remove the hood and trunk deck. Disconnect the race car’s battery by removing the negative cable with a wrench. Mount the battery. Place the battery tray where you want it. Typically, the frame rail directly behind the driver is the best mounting location. Hold the new battery tray against the frame rail and tack it into place with a welder. If you are satisfied with the positioning of the tray, finish welding it in place
