POWERDRIVE 3 – MODEL 26560
3. Reverse the test probes and check the DC plug again (Figure 6-21, Page 6-22). The multimeter should
indicate approximately 922 mV.
4. If multimeter readings are incorrect, check the battery charger wiring (Figure 6-9, Page 6-11).
5. If the multimeter indicates an overload (no continuity) in both directions, and the charger fuse is not
blown, individually check all connections and the continuity of the DC cord and ammeter. See Test Pro-
cedure 8 – Continuity on page 6-23. Also check the rectifier. See Test Procedure 4 – Rectifier on
page 6-20.
6. If the multimeter indicates a voltage reading in both directions, a short circuit exists in the charger DC cir-
cuit, usually caused by a failed rectifier. See Test Procedure 4 – Rectifier on page 6-20. If the rectifier
has not failed, check the DC cord for a short circuit. See Test Procedure 8 – Continuity on page 6-23.
TEST PROCEDURE 6 – TRANSFORMER
See General Warning, Section 1, Page 1-1. See additional WARNING on page 6-1.
Failure of the transformer may be caused by aging or a short circuit in adjacent coil turns. If the transformer
has failed, the ammeter will indicate low output or no output; however, the transformer may hum. A blown AC
line fuse or tripped AC circuit breaker in the charger or the storage facility may be caused by an improperly
wired charger or a failed transformer.
An AC circuit test should be done before performing this test procedure to ensure the continuity of the AC
cord, internal AC circuit breaker, and charger wiring. See Test Procedure 3 – AC Power and Continuity
Test of AC Circuit on page 6-19.
1. Disconnect AC cord from the wall outlet and DC plug from the vehicle receptacle.
2. Remove the charger cover.
3. Disconnect the two black transformer secondary coil wires (1 and 2) from the rectifier (Figure 6-9,
Page 6-11).
4. To apply AC power directly to the transformer primary coil, bypass the relay. See step 4 of Charging a
Battery Pack that has Low Voltage on page 6-34. See following DANGER.

DANGER
• Do not touch any wire or component in the battery charger while AC power is present. Failure
to heed this warning will result in an electric shock.
