1. Check the hydrometer eye that is built into the vehicle's Battery before troubleshooting the Charging System.
- Green eye - Battery is charged.
- Dark eye - Battery is discharged. Recharge Battery.
- Clear or yellow eye - Battery fluid is low. Replace Battery.
2. Check Fuse 4 and Fuse 9.
3. Check the Generator belt.
4. Check that the Starter Solenoid term "B" and Battery connections are clean and tight.
5. Check the vehicle's voltmeter for accurate voltage readings (if equipped).
