Ignition Rotor: Testing and Inspection
Fig. 24 Rotor Inspection - Typical
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.
