Charging System

Such close control falls to the computer system. It is accomplished by monitoring operating conditions and electrical demands. INPUTS (corresponding changes) are then made by the computer to the charging system’s voltage and amperage outputs through signals sent to the voltage regulation circuits and/or engine idle speed control OUTPUTS

Maintenance Tips

• Check battery cables, case and hold-downs, clean terminals, load test
  and check voltage every 20,000 miles
• Check belts every 20,000 miles
• Check battery fluid level every 10,000 miles (except maintenance-free
  batteries)
• Replace belts every 30,000 miles
