TEST OR INSPECTION
When checking voltage in Step 8, red voltmeter lead must be connected to battery
equalizer 24-volt terminal, and black lead must be attached to 12-volt terminal.
Failure to comply may cause damage to equipment.
Prior to taking voltage measurements, ensure all portable handheld radios are fully seated
in their chargers.
Prior to taking voltage measurements, ensure all portable handheld flashlights are
properly connected to their charging cords.
Reconnect all wires/cables that were removed from batteries (WP 0368). Ensure all
portable handheld radios and portable handheld flashlights are properly connected to
their 12-volt charging power source (WP 0004). Check voltage from 12-volt terminal to
GND (ground) terminal on battery equalizer. Check voltage from 24-volt terminal to
12-volt terminal on battery equalizer (using 12-volt terminal as negative connection
If voltage measurements are within 0.1 volt of each other, fault is
If voltage measurements differ by more than 0.1 volt, charge batteries.
If voltage difference continues to exist after charging, replace battery
equalizer (WP 0367).
