## Discrepancy

(CAN) OUR STANDBY ELECTRICAL POWER INOP LIGHT WAS FADING IN AND OUT AT APPROX 65 - 67 PERCENT NG. THE RESISTOR WAS CHECKED OUT AT 110 OHMS AND THEN THE FIELD BRUSHES WERE CHECKED - FOUND THAT TO BE WORN PAST THE POINT OF MAKING CONTACT WITH THE SLIP RINGS. NEW BRUSHES WERE INSTALLED AND THE PROBLEM DID NOT RETURN.
