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.
