BATTERY TESTING PROCEDURE
TEST STEP
(1) Turn headlamps on for 15 seconds.
(2) Turn headlamps off for 2 minutes to allow battery voltage
to stabilize.
(3) Disconnect cables.
OK
Read open circuit voltage.
OK: Open circuit voltage is more than 12.4 V
NG
Charge battery at 5 amps. (see LOAD TEST RATE CHART)
Retest
OK
(1) Connect a load tester to the battery.
(2) Load the battery at the recommended discharge rate (see
LOAD TEST RATE CHART) for 15 seconds.
(3) Read voltage after 15 seconds, then remove load.
(4) Compare the measured value with the minimum voltage (see
LOAD TEST CHART).
OK: Higher than minimum voltage
NG
Replace battery
OK
