6. Make sure the secondary coil wires are not touching one another. With the relay bypassed, insert the AC
plug into an outlet. If the AC line fuse blows or AC circuit breaker trips, the transformer is shorted inter-
nally and must be replaced.
7. If the AC line fuse does not blow or the AC circuit breaker does not trip, check the transformer secondary
coil voltage.
8. Disconnect AC cord from the wall outlet.
9. Using alligator clips and a multimeter set to 500 volts AC, connect the multimeter probes to the second-
ary transformer coil wires (1 and 5).
10. Connect the AC cord to the wall outlet and monitor the multimeter for the secondary coil voltage. If mea-
sured voltage is approximately 85 volts AC or lower for the secondary coil, the transformer is shorted
internally and must be replaced (Figure 4-17, Page 4-18).
11. If the voltage reading is normal (86 volts AC or higher), the transformer is operational. Disconnect the AC
plug from the wall receptacle and check the continuity of the DC circuit. See Test Procedure 5 –
Charger DC Circuit Continuity Test on page 4-16.
12. When troubleshooting and repairs are complete, properly connect the relay wiring. See following
WARNING.

WARNING
• The relay wiring must be properly connected prior to placing the charger back into normal
service. Failure to properly connect the relay wiring could result in property damage, severe
personal injury, or death.
TEST PROCEDURE 7 – BATTERY STATE OF CHARGE TEST
See General Warning, Section 1, Page 1-1.
1. With the batteries fully charged, disconnect the AC charger plug for approximately 20 seconds and then
reconnect it. The ammeter should jump to a reading between 14 and 18 amps and then taper to below
5 amps within 15 minutes.
