Testing the Battery Pack
The electrical function of the battery pack can be measured by using a multimeter and measuring voltage and resistance
across the pins of the connector.
Before Testing
(1)
Examine the battery pack for cracks or other physical damage. If any of these conditions exists, replace the battery pack.
(2)
Fully charge the battery before testing. If the charger failed during the charging process follow these steps below to
determine the cause.
a) Unplug the charger from the outlet to reset the charger’s electronics.
b) Plug the charger back in and connect a different battery to the charger.
c) If the charger fails again during charging the charger is defective and should be replaced. If the charger completes a
successful charge the original battery is defective and should be replaced.
(3)
Align connector/ battery pack like the diagram below.
Figure 1 Diagram 1
Testing the Open Circuit Voltage across the Switch
(1)
Set the multimeter to measure voltage.
(2)
Turn the switch on the battery pack to the "OFF" position.
(3)
Place the positive probe on pin 2 and the negative lead on to pin 3.
(4)
The voltage should read 0 volts.
(5)
Turn the switch to "ON".
(6)
The voltage should now read above 4.8 volts minimum.
Testing the Open Circuit Voltage across the Recharge Circuit
(1)
Set the multimeter to measure voltage.
