DISCHARGE TEST
If the previous tests have failed to identify the problem, conduct a discharge test. The discharge test comes
closest to simulating actual vehicle operating conditions by continuously drawing current from the batteries
until voltage drops to 42.0 volts.
The discharge test is the hardest test on the batteries and the most time-consuming to perform. Use the bat-
tery discharge tester (CCI P/N 101831901).
Performing the Discharge Test
1. Be sure the batteries are fully charged and that the electrolyte level is correct in all cells.
2. Connect the tester leads to the positive (+) post of battery no.1 and negative (–) post of battery no. 4
(Figure 13-5, Page 13-9) .
