HIGH FREQUENCY CHARGER (ONBOARD)

TEST PROCEDURES

See General Warning, Section 1, Page 1-1.

INDEX OF TEST PROCEDURES

1. Battery Voltage Using Multimeter
2. Battery Condition Using Charger – All Batteries
3. On-Charge Battery Voltage Using Charger and Multimeter – All Batteries
4. Hydrometer Test – Flooded Lead-Acid Batteries Only
5. Discharge Test – All Batteries
TEST PROCEDURE 1 – BATTERY VOLTAGE USING MULTIMETER
See General Warning, Section 1, Page 1-1.
1. With a multimeter set to 200 volts DC, measure the voltage of the battery pack between the positive (+)
post of battery no. 1 and the negative (–) post of battery no. 4 (for 4 x 12-volt battery set), battery no. 6
(for 6 x 8-volt battery set), or battery no. 8 (for 8 x 6-volt battery set).
2. Normal no-load voltage should be between 50 and 52 volts for a fully charged battery set. Normal no-load
voltage of an individual battery should not be less than 0.5 volts of the other 7 batteries (for 8 x 6-volt bat-
tery set) or 0.7 volts of the other 5 batteries (for 6 x 8-volt battery set) or 1.0 volt of the other 3 batteries
(for 4 x 12-volt battery set).
TEST PROCEDURE 2 – BATTERY CONDITION USING CHARGER – ALL BATTERIES
The easiest way to monitor the condition of a vehicle's batteries is simply to observe the Charger Information
Light (usually found on the dash) at the end of the charge cycle. After a full charge, disconnect the charger AC
plug, wait 30 seconds and reconnect the charger AC plug. The red LED in the Charger Information Light will
flash quickly and then flash slowly within 10 to 20 minutes, indicating sound, fully charged batteries.
NOTE: Batteries near the end of their useful lives may not allow the battery charge current to taper and the
red Charger Information Light will continue to flash quickly. See Batteries Section in the appro-
priate maintenance and service manual.
Continued poor performance may indicate a problem in the vehicle electrical system, brakes or battery
charger. If the problem is not found in the vehicle or charging system, proceed to the on-charge voltage test.
If the red LED in the Charger Information Light does not change to a slow flash, the batteries should be tested
further using the on-charge voltage test.
TEST PROCEDURE 3 – ON-CHARGE BATTERY VOLTAGE USING CHARGER AND
MULTIMETER – ALL BATTERIES
When the batteries are fully charged, disconnect the charger DC plug. Wait 20 to 30 seconds and reconnect
the DC plug to restart the charger. After 5 minutes, use a multimeter to check and record the voltage of the
battery set as well as the individual batteries. Set the multimeter to 200 volts DC. Place the red (+) probe on
the positive (+) post of battery no. 1 and the black (–) probe on the negative (–) post of battery no. 4 (for 4 x
12-volt battery set), battery no. 6 (for 6 x 8-volt battery set), or battery no. 8 (for 8 x 6-volt battery set). Record
reading. Then set multimeter to 20 volts DC and place the red (+) probe on the positive (+) post and the black
(–) probe at the negative (–) post of each battery. Record the readings.
The on-charge voltage for the set should be between 56.0 volts and 63.0 volts depending on the age and state
of charge of the batteries being tested.
