Troubleshooting
The simple and effective way to spot the defective battery charger is to follow the troubleshooting
procedures (see Fig 11-15).
Continuity inspection
WARNING
To carry out continuity inspection, please see to it to disconnect the battery charger from the AC
and DC mains.
To inspect the continuity, please set the DVOM (digital volt/ohm meter) to kilo-ohm and select "continuity".
The DVOM will send an audible signal when the connection is detected. In case the DVOM has no
connection configuration, then configure the DVOM at kilo-ohm. When the connection is detected, the
DVOM will display "0". (See Fig 11-14)

Diode test procedure
To test the diode, first disconnect the AC supply of the battery charger. After setting the DVOM at the
highest usable ohm range, attach the probe to the diode (see Fig 11-16). In case the reading is not the
given one, the diode is broken. It can be replaced as required.
Procedures for component replacement
To replace the parts, install them in the procedures just reverse to the removal procedures. Any
disconnected wire should be given special attention. Please see to it to install them in their
original places.
