Testing Carbon Pads
The carbon pads can be checked with a DMM. This is done with the resistance setting of the meter. Set the meter to “Ohms.”
Plug one of the test leads into the pin receptacle of the pad. Touch the other lead to the black carbon surface of the pad. If a
resistance of more than 100 Ohms is seen, the pad is beginning to break down and should be replaced.
