Testing Motor and Solenoid Resistances
1.
Turn off the system and disconnect the power cord.
2.
With a DMM set for measuring resistance, test each motor's windings for correct
resistance (disconnected from the system). Rotate the motor's drive shaft slightly
while taking the measurement.

General Troubleshooting
Resistance (Approximate)
4.3 ohms +/-15% (Difficult to measure due to variability at
the brush/commutator interface.)
1.4 ohms +/- 15% (Difficult to measure due to variability
at the brush/commutator interface.)
12.5 ohms/phase (red-to-yellow and blue-to-orange)
1.5 +/- 20% ohms/phase
132 ohms +/- 15%
186 ohms +/- 15%
124 ohms +/- 5%
