Current Output Test

  1. Before performing this test, ensure battery is fully charged. Connect voltmeter leads across battery terminals. Record voltage measured with ignition switch and all accessories off. Fully engage parking brake and place gear selector in Park position.
  2. Start engine and operate at normal operating temperature. Record voltage reading with engine speed at 1800 RPM and no electrical load. Voltage should be no more than 2.7 volts above battery voltage recorded in step 1). If more than 2.7 volts above previously recorded voltage, go to TEST CH-51, CHARGING SYSTEM VOLTAGE HIGH .
  3. Record voltage reading with engine speed at 2400 RPM, blower motor on high and headlights on high beam. Voltage should be more than 0.4 volt above battery voltage previously recorded in step 1). If reading is less than 0.4 volt above previously recorded battery voltage, go to TEST CH-50, CHARGING SYSTEM VOLTAGE LOW. If voltage tests are satisfactory, reduce engine speed, turn off blower motor, headlights and ignition switch.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
