If the speed of the direction indicators on one side is faster than on the other side, then on «fast» side, one of the lamps does not work or the wire is broken.
For all other faults, the turn signal relay is the main cause. The designation of the contacts on the turn relay is usually as follows:
- Contact 31 - «weight».
- Pin 49 - relay input (a constant positive voltage), pin 49a - relay output.
- An additional wire goes to the control lamp on the instrument panel, if there is a tow hitch, there is another wire for the control lamp of the trailer direction indicators.
If a new relay is not available, then carefully insert a thin wire between pins 49 and 49a in the relay socket.
Caution: Do not damage the sensitive contacts of the relay. Bend the ends of the wires so that sharp edges do not stick out. Insert the defective turn signal relay back. The wire should be such that the relay can be inserted into place.
Turn on the ignition. If you now turn on the turn signal with the lever, then the turn indicators will burn constantly. By turning the turn signal lever on and off, you can simulate the flashing of the lamps.
If the direction indicators do not light up, despite the relay contacts being bridged, then the direction indicator switch lever or electrical wires are faulty.
