Checking the device of flashing light signals

The cycles for the device of flashing light signals and for the emergency light signaling system are generated by a relay, the so-called flashing light sensor. The hazard warning light system is connected to a relay without a fuse. The turn signal system is protected by a fuse in the fuse box.

If the rhythm of the flashing device is faster on one side than the other, then on the ''fast" side, the incandescent lamp is faulty or there is an open circuit.

If other defects appear, in most cases the cause is the turn signal interrupter (flash light sensor).

The following terminal positions are indicated on the turn signal breaker:

• Terminal 31 is vehicle ground (minus, in general in the electrical equipment of vehicles).
• Terminal 49 - relay input (positive voltage is constantly applied). Terminal 49a - relay output.
• Terminal C leads to a control lamp on the dashboard, if there is a towing device, there may be an additional terminal C2 to signal the inclusion of the trailer direction indicators.

If you do not have a new relay, carefully insert a thin wire between terminals 49 and 49a in the relay plug.

Attention! do not damage the sensitive relay contacts. Before inserting, bend the ends of the wire so that there are no sharp edges. Reattach the faulty turn signal breaker. Lengthen the connecting bars so that you can put the breaker back on. despite shunting.

Turn on the ignition. If the turn signal lever is now actuated, the corresponding side of the flashing light signal device lights up for a long time. By turning this unit on and off, you can generate a flickering rhythm.

If the flashing light does not light up despite the shunting, the turn signal switch in the electrical supply line is defective.
