The battery circuit is an electrical load on the charging unit. The load is variable because of the condition of the charge in the battery. The alternator may be damaged during operation if the circuit is broken between the battery and the alternator. The damage can occur when the load on the battery suddenly stops. The loss of the load on the battery causes a sudden increase in the voltage. This high voltage can damage the charging unit, the regulator, and other electrical components.The 4C-4911 Battery Load Tester is used to load test a battery that does not hold a charge. Refer to the Tool Operating Manual, SEHS9249 for instructions on the use of the 4C-4911 Battery Load Tester.
