Ignition Coil: Testing and Inspection
INSPECTION OF IGNITION COIL
1. DISCONNECT HIGH TENSION WERE AND IGNITION COIL CONNECTOR
2. CLEAN COIL AND CHECK FOLLOWING:
(a) Check for cracks or damage.
(b) Check the terminals for carbon tracks.
(c) Check the high-tension wire hole for carbon deposits and corrosion.
3. 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 Ohms
4. 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 k Ohms
5. MEASURE INSULATION RESISTANCE
-
Using an ohmmeter, measure the resistance between the positive (+) terminal and the igniter body.
Insulation resistance: Infinity
-
If a problem with the coil is found, replace it.
6. CONNECT HIGH TENSION WIRE AND IGNITION COIL CONNECTOR
