Ignition Ballast Resistor: Testing and Inspection
1.
Disconnect module connector with red and white wires then, ignition coil connector.
2.
Using a suitable ohmmeter, measure resistance between Batt. terminal of ignition coil connector and wiring harness connector wire that joins red
wire in module connector.
3.
If resistance is 0.8---1.6 ohms, ballast resistor is satisfactory. If resistance is less than 0.8 ohms or greater than 1.6 ohms, replace ballast resistor.
