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 buss bar (3)
(Figure 4-24, Page 4-27)
. Test for continuity
between the buss bar and each of the secondary coil wires (tan). The tester should indicate continuity
between the buss bar and both of the 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.
Relay
1. Disconnect the DC cord, the AC cord from the wall outlet, and remove the battery charger from the vehi-
cle.
See Onboard Charger Removal on page 4-35.
2. Remove the charger cover.
3. Remove the black wire from terminal 6 of the relay and black wire from terminal 9 of the relay
(Figure 4-26, Page 4-31)
. Place continuity tester leads on terminals 6 and 9 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.
4. Remove the black wire from terminal 4 of the relay and black wire from terminal 7 of the relay
(Figure 4-26, Page 4-31)
. Place continuity tester leads on terminals 4 and 7 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.
5. Connect charger DC cord to batteries
(Figure 4-6, Page 4-12 through Figure 4-9, Page 4-13)
. Use
jumper wires if necessary. The tester should indicate continuity on relay terminals 6 and 9 and terminals
4 and 7. If tester does not indicate continuity on both sets of contacts, the relay must be replaced.
Ammeter
1. Disconnect the DC cord, the AC cord from the wall outlet, and remove the battery charger from the vehi-
cle.
See Onboard Charger Removal on page 4-35.
2. Remove the charger cover.
3. Disconnect the black wire from the left ammeter post (as viewed from inside the charger).
4. Place the continuity tester clip on one of the ammeter posts.
5. Place the continuity test probe on the other ammeter post. The tester should indicate continuity. If the
tester does not indicate continuity, replace the ammeter.
