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 sensi-
tive to heat.

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.

Reference value
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.
