Check the power supply at the wall outlet. If the outlet is not
delivering 110/120V AC, check the line circuit breaker or fuse.
If the fuse or circuit breaker setting is good, have a qualified
electrician repair the circuit or wall outlet. If the power supply at
the wall outlet is appropriate, check the power supply at the
charger end of the battery charger power cord. If the power
supply at the charger end of the power cord is less than
110/120V AC, replace the power cord (refer to procedure 4.15).
If this solves the problem, go to “Final Actions” on page 2-9. If
not, continue with step 5.
4. Set the voltmeter for DC and check the reading at the battery charger
terminals (J and K).
The voltage measures 27.6V DC (± 2%), and the current measures < 650
mA.
