Starter — check in the car (Audi 80 B3)

1. If the starter does not work, first check the reliability of the electrical wiring to the terminals on the traction relay.

2. Connect a voltmeter or lamp between the large terminal on the traction relay (terminal 30) and a suitable earth point. This terminal is connected directly to the battery and therefore battery voltage should be recorded or the test lamp should light, regardless of whether the ignition is on or not.

3. Disconnect the small wire from the clamp on the traction relay, connect a voltmeter between the wire and ground. Turn on the ignition, battery voltage should be recorded. If not, check the ignition switch and associated wiring. Connect the wire.

4. Connect a voltmeter between the field terminal on the traction relay and ground. Turn the ignition key to the initial position, the voltmeter should indicate battery voltage. If there is no voltage, but there was during the check described in points 2 and 3, the contacts inside the traction relay are defective. If there is battery voltage, but the starter does not work, the damage is in the starter windings, armature or brushes.
