  1. Ensure drive belt is in good condition. Replace belt as necessary. If belt is okay, connect charging system load tester in accordance with manufacturer's instructions. Start and run engine at 2000 RPM, and apply load until generator output levels off. For minimum output specifications, see GENERATOR SPECIFICATIONS  table under GENERATOR SPECIFICATIONS. Go to next step.
  2. Turn A/C system on. Turn blower speed to high. Turn headlights on to high beams. Increase engine speed to 2000 RPM. Voltage should increase a minimum of 0.5 volt above base voltage. If voltage is as specified, system is operating properly at this time. If voltage is not as specified, perform GENERATOR NO-LOAD TEST .
