Insufficiently charged battery

Slow проворачивание the engine or a light surface of the indicator with a red point can testify that the battery is insufficiently charged even if the lamp-index works normally.

The following below procedure can be carried out also by means of the voltmeter or the ampermeter.

 PERFORMANCE ORDER

  1. Be convinced that the given condition does not grow out of that auxiliaries have been left for the long period of time.
  2. Check up a tension drive a belt.
  3. If you suspect that the battery is faulty, the Section the Battery see.
  4. Examine conducting on presence of defects. Be convinced that all connections (connections of a cable for connection of the battery, the starting engine and a cable of grounding of ignition) strong and pure.
  5. Connect the voltmeter and the ampermeter.

The voltmeter

Establish between the generator plug (B) and the grounding plug.

The ampermeter

Establish between the generator plug (B) and positive (+) the battery plug.

Use completely charged battery.

  1. Measure a current strength and pressure.

1 — the generator
2 — the ampermeter
3 — the voltmeter
4 — the battery
5 — a charge (loading)
6 — the switch

Check idling

 PERFORMANCE ORDER

  1. Start the engine with a speed to 2000 rpm and read out indications.
    • Usual current strength: a maximum 10 A
    • Usual pressure:
      • 14.4 – 15.0 V (at temperature 20 C, 85F), type 60 A
      • 14.1 – 15.2 V (at temperature 20 C, 68F), type 70 A and 85 A

Switch off all auxiliaries (yard keepers, a heater etc.).


If pressure and temperature of the case of a regulator vary, this case demands consideration.


Type 60 A.
Type 70 A and 80 A.

High voltage

  1. If pressure more usual, check up grounding of brushes.
  2. If brushes are not earthed, replace regulator IC.

Low voltage

Type 60 A

  1. If pressure normal or below norm, increase speed of the engine to 2000 – 2500 rpm right after start of the engine and immediately measure the maximum indicators of the ampermeter.
  2. If the current strength makes less than 42 A, repair or replace the generator.

Type 70 A and 80 A

  1. If pressure usual, carry out the following check.
  1. Earth plug F and start the engine, then measure pressure in plug B.
  1. Pressure above the usual. It is considered that the generator in a good condition, but regulator IC is damaged. Replace regulator IC.
  2. Pressure below the usual. The generator is faulty, check up the generator.

Pressure check (only 70 A and 80 A)

 PERFORMANCE ORDER

  1. Start the engine with a speed of 2000 rpm and turn head headlights and the heater motor.
  2. Measure a current strength. If it makes less than 20 A (type 70 A) or 30 A (80 A), repair or replace the generator.
