Checking Negative Diodes
1 )
Check the conduction across each M5 screw and coil
connecting terminal (outside).
2) If any diode is faulty, replace its whole negative diode
assembly.
(Important)
• When reassembling, remember that diodes are very
tive to heat.
If the ohmmeter indicates a specified value when the positive
probe is applied to the coil connecting terminal and the nega-
tive probe to the M5 screw, and if it indicates infinity when the
probes are reversed, the negative diodes are normal.

Checking Conduction across N Terminal and
Coil Connecting Terminal
1) Check the conduction across N terminal and coil connect·
ing terminals (inside) .
2) If not conducting, replace.
