Replacing the turn signal relay

Depending on the configuration, an electromagnetic relay-breaker of the RS-950P-T type or an electronic breaker of the 494.3747 or 642.3747 type can be installed on the car.

If the RS-950P-T relay fails, we recommend that you replace the relay assembly, because if the winding is burned out or the contacts are badly burned, it is difficult to restore its operability with high quality.

The design of the relay type 494.3747 or 642.3747 is non-separable.

The turn signal breaker relay is installed on the front panel under the instrument panel on the left side.

Relay test diagram

Electronic breakers type 494.3747 and 642.3747 do not require maintenance during operation.

These breakers cannot be repaired and should be replaced if they fail.

Install the new relay in reverse order.

To remove the relay, disconnect the blocks "B" of the wiring harnesses and unscrew the nuts "A".

To check, remove the RS-950P-T type relay from the car and assemble the circuit (Fig. 1).

If, when the switch is on, 4 lamps are not lit or are lit constantly (not blinking), then inspect the relay contacts.

To do this, remove the relay cover. Clean the burnt contacts with a fine sandpaper, disconnect the baked contacts.

After that, check and, if necessary, adjust the gaps between the contacts.

The gap "a" (Fig. 2) between contacts 3 should be 0.8 mm, and the gap "b" between the core 4 of the relay coil and armature 1 with closed contacts 3 should be at least 0.15 mm.

In order to adjust the gaps, bend the stopper 2 strokes of the armature.
