Test Kc: Step 9

9) Measure AM1/AM2 Solenoid Resistance  Turn key off and wait 10 seconds. Set DVOM on 200-ohm scale. Disconnect AM1 and AM2 solenoid connectors. Measure resistance of both solenoids. If either reading is less than 50 ohms or greater than 100 ohms, replace solenoid assembly and repeat QUICK TEST. If both readings are between 50 and 100 ohms, connect TAB and TAD solenoids. Go to next step.
