1. With the batteries fully charged, disconnect the DC charger plug for approximately 20 seconds and
reconnect it. The ammeter should jump to a reading between 14 and 18 amps and taper to below 5 amps
within 15 minutes.
2. If the charger does not taper to below 5 amps within 15 minutes, batteries may not be receiving a full
charge and the onboard computer should be checked.
See Test Procedure 2 – Onboard Computer on
page 3-21. See following NOTE.
NOTE:
Batteries near the end of their useful lives may not allow the battery charge current to taper below
5 amps.
See Section 13 – Batteries in the appropriate maintenance and service manual.
TEST PROCEDURE 8 – CONTINUITY
See General Warning, Section 1, Page 1-1. See additional WARNING on page 3-1.
AC Cord
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. Disconnect green/yellow wire (2) from charger case and position it so it does not touch any metal part
of the charger
(Figure 3-26, Page 3-26).
4. Disconnect brown wire (1) of AC cord from charger relay terminal 6.
5. Disconnect the blue wire (4) from the charger relay terminal 4.
6. Using a multimeter set for 200 ohms, place the red (+) probe on the terminal at the end of the brown wire
(1). Test for continuity on each of the flat blades and on the round pin of the AC plug. The tester should
indicate continuity on one flat blade only. If any other reading is obtained, the AC cord and plug must be
replaced.
7. Place the red (+) probe on the end of the green/yellow wire (2) and with the black (–) probe check for con-
tinuity on both flat blades and on the ground pin of the AC plug. The tester should indicate continuity on
only the ground pin. If any other reading is obtained, the AC cord and plug must be replaced.
8. Place red (+) probe on the blue wire and check for continuity on both flat blades and on the round pin of
the AC plug. The tester should indicate continuity on only one flat blade. If any other reading is obtained,
the AC cord and plug must be replaced.
