INSPECTION OF IGNITION COIL
1. DISCONNECT HIGH-TENSION CORD
2. MEASURE COIL RESISTANCE
(a) Disconnect ignition coil connectors.
(b) Measure primary coil resistance.
Using an ohmmeter, measure the resistance between the positive (+) (brown side) and negative (—) (black side) terminals.
Primary coil resistance (cold): 0.4 — 0.5 Ω
(c) Measure secondary coil resistance.
Using an ohmmeter, measure the resistance between the positive (+) terminal (brown side) and the high tension terminal.
Secondary coil resistance (cold): 8.5 — 11.5 kΩ
3. CONNECT HIGH-TENSION CORD
ON-VEHICLE INSPECTION OF DISTRIBUTOR
1. INSPECT DISTRIBUTOR CAP AND ROTOR
(a) Check for cracks, carbon tracks, burnt or corroded terminals.
(b) Check the distributor center contact for wear.
If a problem is found, replace the component.
2. CHECK PICKUP COIL
Using an ohmmeter, check each resistance of the two pickup coils.
G pickup coil resistance:
G — G(—) 140 — 180 Ω
Ne pickup coil resistance:
Ne — G(—) 140 — 180 Ω
If the resistance is not correct, replace the distributor.
