Battery Test (continued)
3. Test each battery separately.
4. Using a digital voltmeter which can be read to 0.01 vdc, check the voltage
across the posts of the batteries, one at a time. Record the voltage readings for each
battery. If the voltage does not read at least 12.40 vdc, the battery probably should
be replaced. You may try to recharge the battery, but it probably won't hold a
charge. For replacement procedure see Paragraph 4.6.5.
5. If the battery's voltage is satisfactory, use the battery tester. Attach the red
battery tester cable to the positive (+) battery pole; attach the black cable to the
negative (-) battery pole.
6. Press the LOAD switch. (If using a brand of tester other than the Balkamp,
follow the tester's operating instructions.)
7. In approximately 10 seconds, the tester needle should be in the "good"
(green) area. If not, the battery should be replaced.
8. Perform the same tests on all batteries in the cabinet. (Allow the tester to
cool between tests.)
9. For proper operation, each battery in the cabinet should show voltage
readings within ±0.10 vdc of their average. If full agreement of battery voltages
cannot be obtained, contact
Service Hotline 800-777-8922.
10. Return the battery trays to their normal position. When each tray is fully
back, replace the two bolts that fasten it to the slide. Reconnect the battery tray
cables.
