Bench Testing: Stator
- Place ohmmeter on lowest scale. Measure resistance between 2 of the 3 sets of wires. Move one ohmmeter lead to the other set of wires. Check resistance between the remaining set of wires. Resistance values must be identical. If resistance is incorrect, stator has open or shorted windings and must be replaced.
- Place ohmmeter on X1000 scale. Connect ohmmeter between stator core and each stator lead. Continuity should not exist. If continuity exists, stator is grounded and must be replaced.
