Resistor AssemblyExcept HBF2 Models
Only perform this check after completing Motor Tube Wiring checks
INote To avoid damaging components or troubleshooting equipment, disconnect the battery cables before proceeding
1Turn the speed control switch to OFF
2Remove the motor from the adapter housingDo not disconnect the motor leads at this time
3Use an ohmmeter calibrated on low ohms scale to test the condition of the resistor
rn 4Connect the ohmmeter between the RED and the GREEN resistor terminals:
The meter should show 0.17-0.23 ohm If measured resistance is significantly different AND motor does not respond to speed control change, replace resistor
rn 5Connectterminals: between the GREEN and GREENI the ohmmeter WHITE resistor
