Ignition Resistor: Testing and Inspection
DS III
Ballast resistor test connections
1.
Disconnect and inspect module two wire connector and ignition coil connector, Fig. 8.
2.
Using a suitable ohmmeter, measure resistance between coil connector Batt. terminal and wiring harness connector which mates with module red
wire, Fig. 8.
3.
If reading is 0.8---1.6 ohms, circuit is satisfactory. If reading is less than 0.8 ohms or more than 1.6 ohms, replace ballast resistor.
