ELECTRICAL SYSTEM 10-21
IGNITION COIL/PLUG CAP RESISTANCE
• Remove the radiator mounting bolt. (10-20)
• Remove the ignition coil/plug cap and disconnect its coupler.
Measure the ignition coil/plug cap resistance in both the primary
and secondary windings. If the resistance is not within the stan-
dard range, replace the ignition coil/plug cap with a new one.
