- Test for less than 2 ohms between the test points: B+ circuit terminal 1 & Output terminal @Fuse
- If 2 ohms or greater - Repair the open/high resistance in the circuit.
- If less than 2 ohms - Repair the open/high resistance in the ground connection.
- Go to next step: If the test lamp turns On
- Test or replace the component: G10 Cooling Fan Motor
