Diagnostics of malfunctions of a starter without its removal from the car

Before starting diagnostics of a starter make sure that the battery is completely charged.

If the starter does not join in general, make sure that the lever of the selector is installed in the correct situation ("Р" or "N") (AT), or the pedal of coupling (RT) is squeezed out.

Make sure that the battery is charged, and plugs and tips of all wires (on the battery and the traction relay) are not damaged by corrosion and reliably fixed.

If the starter rotates, but does not scroll the engine, it speaks about pro-slipping of the obgonny coupling in a starter and need of replacement of the last.

If after inclusion the starter does not begin to rotate, but the click published when switching the traction relay is clearly heard, the problem is covered in malfunction of the battery, violation of contacts or failure of the starter (if of course the engine is not jammed).

If the plunger of the traction relay does not click, switching at inclusion of a starter, then either the battery is faulty, or the fusible insert fused (a gap in a chain), or defect of the relay takes place.

 PERFORMANCE ORDER

  1. For check of serviceability of the relay connect a wire from a set for start of the car from an auxiliary source between positive (+) the plug of the battery and the small plug of a wire of the lock of ignition on the relay. If now the starter joins, the relay as it should be and a problem in malfunctions of the lock of ignition, the switch of permission of start, the relay of start or an electrical wiring.
  2. Find the start relay in distribution center of power supply. Take out the relay and make its check (it is absolutely similar to check of the ASD relay and fuel pump in the Section Check of Pressure of Fuel and Functioning of the Fuel Pump of the Head of the Power Supply System and production of the fulfilled gases (see also illustrations "Measure Resistance between Plugs 86 and 85..." and "Also Measure Resistance between Plugs 30 and 87A..." in the Head of the Power supply system and production of the fulfilled gases).

Location of distribution center of power supply (shooter).

Location of the relay of start.

  1. If the starter still does not rotate, remove it together with the relay for carrying out dismantling, detailed diagnostics and repair/replacement.
  2. If the starter turns the engine too slowly, first of all check the level of a charge of the battery and a state and reliability of fastening of all terminal connections. Partial jamming of the engine or filling with its oil of too high degree of viscosity can also be the reason of its slow provorachivaniye a starter.
  3. Start the engine and let's it get warm up to the normal working temperature, then disconnect a coil wire from a cover of the distributor and ground it on the mass of the engine.
  4. Connect a positive wire of the voltmeter to the positive plug of the battery, and negative - to negative.
  5. Turn the engine and consider indications of the voltmeter. Do not include a starter continuously more than for 15 seconds. The indication over 9 V at the starter rotating with a normal speed is considered norm. If instrument reading is higher than 9 V, but the speed of a provorachivaniye is insufficient, it is necessary to check a condition of contacts of the traction relay or electric sockets of a contour. If voltage below 9 V is fixed and the speed of rotation is insufficient, most likely the starter is faulty.
