Resistor AssemblyHBF2 Only perform this check after completing Motor Tube Wiring HBF2 checks1Remove two thru-bolts and remove motor drive-end head, motor field, and motor armatureDo not lose armature brush springs2Use an ohmmeter calibrated on high ohms scale or continuity light to test continuity rn rn
3Connect one meter lead to top starboard brush wire in adapter housingLeave this lead on the brush wire for all of the following tests4Connect other ohmmeter lead alternately to GREEN! WHITE, GREEN, and RED wires at speed control switch terminals "3", "4", and "2": Meter must show continuity with each lead If any lead shows no continuity, repair wire, or replace complete adapter housing, resistor coils, and wires5Connect second meter lead to adapter housing: Meter must show no continuity If meter shows continuity, repair wire or replace adapter assembly6Repeat Steps and with an ohmmeter calibrated on the low ohms scale to check the resistance values of the wires and resistors
