SPARK PLUGS
Refer to "ELECTRICAL" in chapter 3.
SPARK PLUG CAPS
1. Inspect:
Spark plug cap
G
Loose → Tighten.
Cracks/damage → Replace.
IGNITION COIL
1. Measure:
Primary coil resistance
G
Out of specification → Replace.
Primary coil resistance:
Orange (O) – Black (B)
0.078–0.106 Ω at 20 ˚C (68 ˚F)
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".
