WARNING
When the charger is connected to the power supply with
housing removed, it has lethal voltage when the cover is
removed. If you suspect your ability to safely perform the
following tests, you can ask the trained
electrician/technician to repair the charger.
Please extremely careful not to make the non-insulated part
of the testing spike touch any other parts or the charger
frame.
NOTE
Attach the test lead to the wires on two sides of the fixed
relay printed circuit board so as to shunt the relay. Plug the
charger into the AC electrical outlet, the transformer may
buzz. This means that the primary coil is in operation, but
the printed circuit board breaks down. In case the
transformer doesn't buzz, the transformer is broken.
