Snubber Circuit
Snubber circuit check:
With an ohmmeter set to the R x 1 scale or the diode check setting,
measure across each diode in the circuit. You should see a resistance
reading typical of a diode, with low resistance in one direction and high
resistance in the other direction. The resistors can also be checked with an
ohmmeter by measuring across each resistor. The snubber capacitors
should be checked for physical damage and may also be checked with an
ohmmeter. A high resistance value should be present. Refer to the
Appendix of this document for detailed specifications for the snubber diode,
resistor and capacitor.
