3. Carefully cut the heatshrink that insulates the AC cord white wire (4) where it connects to the tan primary
coil wire
(Figure 5-17, Page 5-20)
.
4. Disconnect terminals from transformer (tan and black) primary coil transformer wires (4 and 6)
(Figure 5-16, Page 5-19)
.
5. Place the continuity tester probes on the disconnected primary coil wires. The tester should indicate con-
tinuity. If tester does not indicate continuity, replace the transformer.
6. If the correct readings were obtained, install the AC cord and connect the transformer primary coil wires.
See AC Cord Installation on page 5-29.
Secondary Coil
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. Remove the transformer (black) secondary coil wire (1) from the rectifier
(Figure 5-16, Page 5-19)
.
4. Remove the other transformer (black) secondary coil wire (5) from the rectifier.
5. Place the continuity tester probes on the disconnected secondary coil wires. The tester should indicate
continuity. If tester does not indicate continuity, replace the transformer.
Voltage Suppressor – Failed Closed
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. Using a multimeter set to the diode test function (
ç
), place the black (–) probe of the multimeter on the
sense lead pin (short pin) of the DC plug. Place the red (+) probe on the positive (+) pin of the DC plug.
The multimeter should indicate no tone. If a tone is emitted (indicating a closed circuit) then the voltage
suppressor has failed and should be replaced.
See following NOTE.
NOTE: All vehicles except Precedent:
Repeated failure of sense lead fuses is a symptom of a voltage
supressor that has failed in a closed condition.
Precedent vehicles only:
Failure of the onboard computer due to a blown internal sense lead
fuse is a symptom of a voltage supressor that has failed in a closed condition.
Relay
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. Remove black wires (3 and 4) from contact terminals of the relay
(Figure 5-6, Page 5-8)
. Place conti-
nuity test probes on contact terminals of the relay. The tester should indicate no continuity. If tester indi-
cates continuity, the relay contacts have failed closed and the relay must be replaced.
4. Place continuity test probes on contact terminals of relay. With batteries connected, insert DC plug into
receptacle. The tester should indicate continuity. If tester does not indicate continuity, relay must be
replaced.
Ammeter
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. Disconnect the white wire from the left ammeter terminal (as viewed from inside the charger).
4. Place the continuity tester clip on one of the ammeter posts.
