Is the resistance below 5.0 ohms?
Yes → Go To 4
→ Repair the open in the (K20) Gen Field Control circuit.
No
4 Measure the resistance between ground and the (K20) Generator Field Control
circuit in the PCM harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (K20) Gen Field Control circuit.
→ Go To 5
No
5 Measure resistance across the Generator Field Terminals at the Generator.
Is the resistance between 0.5 of and ohm and 15 ohms?
Yes → Go To 6
→ Repair the Generator as necessary.
No
