1984-86 Models
1. Disconnect harness connector at resistor located near ignition coil, Fig. 19.
2. Measure resistance across terminals 1 and 2, then 1 and 3. Resistance should read approximately as shown, Fig. 20. If resistor reads 0 ohms or infinity, replace resistor.
3. Install resistor, then firmly connect connector.
