IGNITION COIL INSPECTION
NOTICE: ”Cold” and ’Hot” in the following sentences ex–
press the temperature of the coils themselves. ”Cold’ is
from –10 C (14 F) to 50 C (104 F) and ”Hot’ is from
50 C (104 OF) to 100 C (212 OF).
1. DISCONNECT HIGH–TENSION CORD
2. CLEAN COIL AND CHECK FOLLOWING:
(a) Check for cracks or damage.
(b) Check the terminals for carbon tracks.
(c) Check the high–tension cord hole for carbon deposits
and corrosion.
DISTRIBUTOR INSPECTION
1. INSPECT AIR GAP
Using a thickness gauge, measure the gap between
the signal rotor and the signal generator (pickup coil)
projection.
Air gap:
0.2–0.4mm(0.008–0.015in.)
4. MEASURE SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between
the positive (+) terminal and high–tension terminal.
Secondary coil resistance (Cold):9.0 –15.4k
Secondary coil resistance (Hot) :11.4–18.1 k
5. CONNECT HIGH–TENSION CORD
3. MEASURE PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between
the positive (+) and negative (–) terminals.
Primary coil resistance (Cold):0.36–0.55

Primary coil resistance (Hot) :0.45–0.65
