lgnition System
lgnition Coil Test
Using an ohmmeter, measure resistance between the
terminals. lf the resistance is not within soecifications,
replace the ignition coil.
NOTE: Resistance will vary with the coil temperature;
specifications are at 68'F (20'C).

lgnition Wire Inspection and Test
C A U T I O N : C a r e f u l l y r e m o v e t h e i g n i t i o n w i r e s b y
pulling on the rubber boots. Do not bend the wires; you
might break them inside.
1. Check the condition of the ignition wire terminals. lf
anv terminal is corroded, clean it. and if it is broken
or distorted, replace the ignition wrre.
Check for broken,
corroded, and benl
terminals.
IGNITION WIRE
2.
Connect ohmmeter probes and measure resistance.
lgnition Wire Resistance:
25 kO max. at 68'F (20"C)
IGNITION WIRE
3. lf resistance exceeds 25 kO, replace the ignition wire.
