Ignition Coil: Testing and Inspection

INSPECTION OF IGNITION COIL

1. DISCONNECT HIGH-TENSION CORD





2. INSPECT PRIMARY COIL RESISTANCE

Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.

Primary coil resistance (cold): 0.24-0.30 ohms





3. INSPECT SECONDARY COIL RESISTANCE

Using an ohmmeter, measure the resistance between the positive (+) terminal and high-tension terminal.

Secondary coil resistance (cold): 9.2 - 12.4 kohms

4. RECONNECT HIGH-TENSION CORD
