3. Disconnect green/yellow wire (2) from charger case and position it so it does not touch any metal part
of the charger
(Figure 5-18, Page 5-24)
.
4. Using a multimeter, set for 200 ohms, place the red (+) probe on the terminal at the end of the black wire
removed from relay terminal 4 (4)
(Figure 5-18, Page 5-24)
. Test for continuity on the appropriate pin of
the AC charger receptacle (on front of charger). The tester should indicate continuity on the ground pin
only. If any other reading is obtained, the AC charger receptacle or connecting wires have failed and must
be replaced.
5. Put the red (+) probe on the end of the green/yellow wire (2) and with the black (–) probe check for con-
tinuity on the appropriate pin of the AC charger receptacle
(Figure 5-18, Page 5-24
and
Figure 5-6,
Page 5-9)
. The tester should indicate continuity on the ground pin only. If any other reading is obtained,
the AC charger receptacle or connecting wires have failed and must be replaced.
6. Disconnect black wire from charger relay terminal 8 (8)
(Figure 5-18, Page 5-24)
. Put the red (+) probe
on the black wire (8) and check for continuity on the appropriate pin of the AC charger receptacle. The
tester should indicate continuity on the ground pin only. If any other reading is obtained, the AC charger
receptacle or connecting wires have failed and must be replaced.
DC Cord
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. To check the continuity of the DC cord, disconnect the black wire (17) of the DC cord from the ammeter
(Figure 5-19, Page 5-25)
.
4. Disconnect the red wire (19) of the DC cord from the heatsink.
5. Disconnect the blue wire (18) from the limiter (15), which connects to the red wire assembly that connects
to the charger relay.
