3. Observe the status indicator lights on the charger to
determine if it has power and is charging.
NOTE: Refer to the manual supplied with the charger for
status indicator light information.
— If the off-board charger status indicator lights do not
turn on, then go to the next step.
— If the off-board charger status indicator lights turn on
and indicate that the charger is charging, then allow the
batteries to charge for 8-14 hours and retest the system.
— If the off-board charger status indicator lights indicate
that the charger has power but is not charging, then
replace the off-board charger (11) and retest the system.
4. Unplug connector 12a from connector 11a. See dia-
gram 2. (If the charger power cord is hardwired to the
off-board charger, then go to step 6).
5. Measure voltage across pin 1 and pin 2 and across pin 1
and 3 of connector 12a. See figure 13.
— If the multimeter indicates about 120VAC for both tests,
then replace the off-board charger (11) and retest the
system.
— If the multimeter does not indicate about 120VAC for
both tests, then go to the next step.
From step 4
6. Unplug connector 12b from the electrical outlet.
7. Measure voltage across pin 2 and pin 3 and across pin 1
and pin 3 of the electrical outlet. See figure 14.
— If the multimeter indicates about 120VAC for both tests, then replace the power cord (12) and retest the system. (If
the power cord is hardwire to the charger, then replace the off-board charger (11) and retest the system.)
— If the multimeter does not indicate about 120VAC for both tests, then try a different electrical outlet and retest the
system.
From step 1
8. Remove the front shroud. See figure 6.
9. Measure voltage across connectors 6b and 7c. If 0VDC is read, then measure voltage across connectors 6c and 7b.
See diagram 3.
— If the multimeter indicates the same voltage as measured in step 1, then the batteries are too low to charge with the
off-board charger. Take the batteries to an authorized service center for load testing and charging.
— If the multimeter indicates a different voltage than measured in step 1, then go to the next step.
10. Unplug connector 5a from connector 2d. See diagram 2.
11. Measure voltage across pin 1 and pin 2 on connector 5a. See figure 15.
— If the multimeter indicates the same voltage as measured in step 9, then go to step 16.
— If the multimeter indicates a different voltage than measured in step 9, then go to the next step.
