6. Place the clip of the continuity tester on the red wire (19) of the DC cord.
7. Place the continuity test probe on the positive (+) pin of the DC plug (positive (+) and negative (–) pins
are identified on the plug). If tester does not indicate continuity, the DC cord must be replaced.
8. Place the continuity test probe on the negative (–) pin of the DC plug. The tester should indicate no con-
tinuity. If tester indicates continuity, the DC cord must be replaced.
9. Place the continuity test probe on the unmarked (middle) pin of the DC plug. The tester should indicate
no continuity. If tester indicates continuity, the DC cord must be replaced.
10. Move the continuity tester clip to the black wire (17) of the DC cord.
11. Place the continuity test probe on the negative (–) pin of the DC plug. The tester should indicate conti-
nuity. If tester does not indicate continuity, the DC cord must be replaced.
12. Place the continuity test probe on the unmarked (middle) pin of the DC plug. The tester should indicate
no continuity. If tester indicates continuity, the DC cord must be replaced.
13. Move continuity test probe to the blue wire (18) of the DC cord. Check for continuity at the middle pin.
The tester should indicate continuity. If tester does not indicate continuity, replace DC cord.
Transformer
The IQ Plus battery charger transformer has two sets of coils: a primary coil and a secondary coil.
Primary Coil
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. Disconnect the black wires marked 1 and 6 from the AC circuit breakers.
4. Disconnect the wires marked 2, 3, 4 and 5 from the voltage selector switch.
5. Place the continuity tester probes on the primary coil transformer wires disconnected above in pairs until
all of the combinations in the following chart have been tested.
6. If the continuity readings agree with the chart, replace the voltage selector switch. If the continuity read-
ings differ from the chart, replace the transformer.
