SPARK PLUGS
Refer to “ELECTRICAL” in chapter 3.
SPARK PLUG CAPS
1. Inspect:
●
Spark plug cap
Loose
→
Tighten.
Cracks/damage
→
Replace.
IGNITION COIL
1. Measure:
●
Primary coil resistance
Out of specification
→
Replace.
NOTE:
When measuring a resistance of 10
Ω
or
less with the digital tester, the correct mea-
surement cannot be obtained because of
the tester’s internal resistance.
Refer to “Low resistance measurement”.
Primary coil resistance:
Orange (O) – Black (B)
0.078–0.106
Ω
at 20 ˚C (68 ˚F)
