BATTERY TROUBLESHOOTING EXAMPLES

The following information represents a few examples of troubleshooting battery problems.
Example 1
Vehicle No. 68 was suspected of having a defective battery due to its performance. As a result, the battery charger
test was performed. After a full charge, the battery charger ammeter read 8.0 amps. Next, the on-charge voltage test
was performed and the following results were recorded:
BATTERY NO.
ON-CHARGE VOLTAGE
*Battery No. 3 appears to be suspect. Battery Nos. 1 and 4 are also suspect. Next, a hydrometer test should be con-
ducted on all batteries.
Hydrometer test results:
BATTERY NO.
CELL 1 (POSITIVE POST)
CELL 2
CELL 3
CELL 4 (NEGATIVE POST)
*After the hydrometer test, it appears that battery No. 1 is the problem. Next, the discharge test was performed.
Discharge test results:
BATTERY NO.
DISCHARGE VOLTAGE
*After a discharge test which lasted 45 minutes, battery No. 1 is clearly shown to be the problem. Battery No. 4
should be watched a little more closely but appears to be okay. Battery No. 1 should be replaced with a battery that
has about the same age and usage as the other batteries.
Example 2
Vehicle No. 70 was also suspected of having a defective battery due to its performance. The battery charger test
showed 7.0 amps after a full charge. After confirming there were no problems with the electrical system, charger or
brakes, the on-charge voltage was recorded as follows:
BATTERY NO.
ON-CHARGE VOLTAGE
*Battery No. 2 was immediately suspected as the problem. After checking battery No. 2 with a hydrometer, it was
discovered that the negative post cell was completely dead. Battery No. 2 should be replaced with a battery that has
the same age and usage as the other batteries.
