Incomplete

1. Prior to the inspection, make sure that the battery cables are connected securely.
2. When a quick charging operation is carried out, first be sure to disconnect the battery cables.
3. Never use a high-voltage insulation resistance tester for the purpose of conducting this inspection.
4. Under no circumstances should the battery cables be disconnected while the engine is rotating.

1. Prior to the in-vehicle inspection, be sure to perform the following checks.
   1. Specific gravity of battery electrolyte
   2. Installation of battery terminals
   3. Tension of V-belt
   4. Fuse
   5. Wiring harness
   6. Abnormal noise emitted from alternator while engine is rotating
2. Output test under unloaded state
   1. Ensure that all switches are turned OFF so that no unnecessary electric load may be applied.
      • Headlamps
      • Heater blower
      • Radio
      • Rear defogger
      • Room lamp, etc.
   2. Raise the engine revolution speed gradually to 2500 грm.
      Measure the current and voltage at 2500 rpm.
      Specifications:
      • 10 A or more
      • 14.2 - 14.8 V
   3. NOTE:
      • Immediately after the engine starting, the current may jump to 10 A or more momentarily. This is not an abnormal phenomenon.
      • If the voltage reading i s less than the standard voltage, ground the terminal F as indicated in the right figure. Proceed to start the engine.
      • If the voltage reading becomes greater than the standard voltage under this setting, replace the IC regulator.
      • If the voltage reading is still less than the standard voltage under this setting, check the alternator.
3. Output test under loaded state
   1. To apply electric load, perform the following operation.
      1. Set the headlamps to the upper-beam position.
      2. Set the heater blower to the “High” position.
   2. Measure the output current of the alternator at the engine speed of 2500 rpm.
      • Specified Value: 20 A or more
   3. NOTE:
      • When the battery is fully charged, the measured current may be below the specified value. This is not an abnormal phenomenon.
      • At this time, increase the electric load, for example, by turning ON the rear defogger.
      • Then, check to see if the output current rises or not.
