Ignition Rotor: Testing and Inspection
Fig.29 Rotor Inspection - Typical
DIAGNOSIS AND TESTING - IGNITION ROTOR
Visually inspect the rotor for cracks, evidence of corrosion or the effects of arcing on the metal tip. Also check for evidence of mechanical interference
with the cap. Some charring is normal on the end of the metal tip. The silicone-dielectric varnish compound applied to the rotor tip for radio
interference noise suppression, will appear charred. This is normal. Do not remove the charred compound. Test the spring for insufficient tension.
Replace a rotor that displays any of these adverse conditions.
