Engine System Activation Load Test
Start the engine to make the tester automatically records the lowest voltage. For a 12 V system, the default voltage is 9.6 V; for a 24 V system, the default voltage is 16 V. If the lowest voltage is higher than 9.6 V (for a 24 V system, the lowest voltage is higher than 16 V), the system is OK. If the lowest voltage is lower than the standard voltage, the system is not OK.

System Test at Maximum Load
For the 12V system, the standard voltage is 12.8V, for the 24V system, the standard voltage is 25.6V. If the lowest voltage is higher than 12.8V (for the 24V system, the lowest voltage is over 25.6V), the system runs normally. If the lowest voltage is lower than 12.8V (for the 24V system, the lowest voltage is under 25.6V), please check if the engine belt is damaged and the wires are short-circuited.

Test of the Charging System
For the 12 V system, the standard voltage is 12.8 V and for the 24 V system the standard voltage is 25.6 V. If the lowest voltage is higher than 12.8 V (for the 24 V system, the lowest voltage is higher than 25.6 V), the system runs normally. If the lowest voltage is lower than 12.8 V (for the 24 V system the lowest voltage is lower than 25.6 V), please check if the engine belt is damaged and the cables are short-circuited.
