3.3.8.2. The starter electric motor
THE GENERAL DATA

Starter wires

1. A wire from the battery
2. A wire on the generator
3. The tyre connecting a power exit with a starter
4. A conclusion 50

On models 1988-1990 there is an additional wire (in a picture is absent).

Rack of a soaking up collector and nut of fastening of a rack on cars with the 4-cylinder engine

1. The switch throttle заслонки
2. A soaking up collector

Bolts of fastening of a starter are specified by arrows.


The prevention

Before starter check be convinced that the battery is completely charged.


Check without removal from the car

PERFORMANCE ORDER
1. If the starter electric motor does not rotate at all at key turn be convinced that the selector lever is in position Park or Neutral (on cars with automatic transmission).
2. Be convinced that the battery is charged, check up cleanliness reliability of fastening of power cables.
3. If at turn of a key the starter electric motor joins, and коленвал is not turned, the reason is проскальзывание обгонной муфты a starter. In this case it is necessary to replace a starter.
4. If at turn of a key the starter electric motor does not rotate, but clicks of the traction relay contacts of the traction relay are faulty, the battery or the starter electric motor (or it is hardly turned коленвал) are distributed.
5. If at inclusion of a starter the click published by an anchor of the relay, is not listened, causes of a failure can be malfunction of the battery, blowing a fusible crosspiece, malfunction of the traction relay.
6. For check of the traction relay перемкните on the relay a conclusion for battery connection (+) and a conclusion for a wire from the ignition key (the small plug). If the starter electric motor is started, the traction relay is serviceable, and the ignition key, the auxiliary relay of a starter or conducting are faulty.
7. If the starter electric motor still is not started, remove a starter for dismantling, check and repair.
8. If the starter turns коленвал, but with very small speed at first check up degree заряженности batteries and reliability of connections. The starter will rotate the engine with small speed also in those cases if hardly rotates коленвал or in the engine oil with too big viscosity is filled in.
9. Warm up the engine, then disconnect a high-voltage wire of the coil from a cover of the distributor and connect to weight on the engine.

10. Connect the voltmeter. Include a starter and consider the established indication of the voltmeter. Time of inclusion of a starter should not exceed 15 seconds. Pressure on the battery at normal speed of rotation коленвала should be 9 In or a bit more. If pressure on the battery is equal 9 In, or exceeds 9 In, and speed of rotation коленвала low the starter electric motor is faulty a little. If pressure is less 9 In, and speed of rotation коленвала low plausible reasons are malfunction of a starter or the battery.


The prevention

The starter in gathering with the traction relay is not subject to independent repair, despite presence on sale of necessary spare parts. In default replace a starter or hand over in repair.


Removal and installation

PERFORMANCE ORDER
1. Disconnect the battery from weight.
2. Lift car redock.
3. Designate and disconnect from a starter all wires.
4. On a part of cars for access to a starter it is required to remove the air filter, a broad tank and hoses of system of cooling.
5. On a part of cars with the 4-cylinder engine turn away bolts and nuts and remove a rack of a soaking up collector, remove a starter.
6. Installation is carried out upside-down.
