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 amps 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 battery dis-
charge tester (CLUB CAR Part No.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. 6.

3. Check and record the electrolyte temperature of the battery packs. Check cell No. 2 in each battery (second
cell from positive post).
4. Reset discharge machine and turn the tester ON.
5. When the batteries have been discharging for approximately 60 minutes, set the discharge machine to function 3
and check battery set voltage. Check voltage every 10 minutes throughout the rest of the test. As soon as the battery
