ELECTRICAL SYSTEM
Rectifier
1. Check the continuity of each diode of rectifier with an analog
ohmmeter. Conduct the test in the (R × 1) setting.
2. The rectifier is normal if the diode in the rectifier conducts in one
direction and does not conduct in the reverse direction.
IMPORTANT■
• Do not use a 500 V megger for measuring because it will
destroy the rectifier.
NOTE■
• Do not use an auto digital multimeter. Because it’s very hard
to check the continuity of rectifier by using it.

IC Regulator
1. Check the continuity of the terminal B and the terminal F of IC
regulator with an analog ohmmeter. Conduct the test in the (R ×
1) setting.
2. The IC regulator is normal if the IC regulator conducts in one
direction and does not conduct in the reverse direction.
IMPORTANT■
• Do not use a 500 V megger for measuring because it will
destroy the IC regulator.
NOTE■
• Do not use an auto digital multimeter. Because it’s very hard
to check the continuity of IC regulator by using it.
