If the rhythm of the flashing device is faster on one side than on the other, then the bulb on the "fast" side is faulty or there is an open circuit.
If other defects occur, in most cases the cause is the turn signal interrupter (flashing light sensor).
The following terminal positions are indicated on the turn signal switch:
- Terminal 31 is the vehicle ground (minus, in general, in the electrical equipment of vehicles).
- Terminal 49 - relay input (positive voltage is supplied constantly). Terminal 49a - relay output.
- Terminal C leads to a warning light on the instrument panel, if a towing device is present there may be an additional terminal C2 to signal that the trailer direction indicators are on.
If you do not have a new relay, carefully insert a thin wire between terminals 49 and 49a in the relay plug connector.
Caution! Do not damage the sensitive relay contacts. Before inserting, bend the ends of the wire so that there are no sharp edges. Re-attach the faulty turn signal flasher. Extend the connecting busbars so that you can re-attach the flasher despite the bypass.
Switch on the ignition. If the turn signal lever is now activated, the corresponding side of the flashing light device lights up for a long time. By switching this device on and off, a flickering rhythm can be formed.
If, despite the bypass, the flashing light does not light, then the turn signal switch in the electrical supply line is faulty.
