Distributor Hardware Test
- Disconnect distributor 3-way pigtail. Connect voltmeter leads between Orange wire (pin No. 3) and Purple wire (pin No. 7). Crank engine and observe voltmeter. Voltmeter needle should oscillate. If needle does not oscillate, remove distributor cap and check for damage or incorrect assembly.
- Armature must be tight on sleeve and roll pin, aligning armature, in position. Iron stator must not be broken and armature must rotate when engine is cranking. If internal components are okay, and voltmeter needle still will not oscillate, replace magnetic pick-up (stator assembly).
