DIAGNOSIS AND TESTING - DISTRIBUTOR
ROTOR - 5.9L V-8
Visually inspect the rotor (Fig. 29) for cracks, evi-
dence 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 sup-
pression, 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.
