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 (tan) secondary coil wire from the upper terminal of the heatsink
(Figure 5-15,
Page 5-21)
.
4. Remove the other transformer (tan) secondary coil wire from the bottom terminal of the heatsink and
place the continuity test clip on the ammeter post with the short black jumper wire (7)
(Figure 5-20,
Page 5-30)
. Test for continuity between the jumper wire and each of the secondary coil wires (tan). The
tester should indicate continuity on both secondary coil wires. If tester does not indicate continuity on
both secondary coil wires, replace transformer. Ensure that the fuse is intact and not blown.
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:
Repeated failure of sense lead fuses 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 the black wire from terminal 6 of the relay and black wire from terminal 8 of the relay
(Figure 5-6, Page 5-9)
. Place continuity tester leads on terminals 6 and 8 of the relay. The tester should
indicate no continuity. If tester indicates continuity, the relay contacts have failed closed and the relay
must be replaced.
