Haasad. I have not been following this thread so if I restate something already said, my appologies.
If you have not changed any of the connected wires then I believe the problem is the flasher itself. I believe Ray mentioned that as well. I will attach a pic of the flasher relay because I believe you said that you had changed that earlier. Just check the connections on the relay to make sure they are the same as my drawing. I don't have a pic of the flasher handy but as Ray said, you must use a flasher with 3 terminals, looking at the back of the flasher, the terminal to the top left is "L" it should have a green/brown wire on it and it goes to the #1 terminal on the relay which is the top right terminal. That is actually power out to the relay and then thru the relay and on to the turn signal bulbs on the fenders. On the top right terminal of the flasher is terminal "B"
and it should have a green wire on it. This is power coming into the circuit from the top fuse in the 2-fuse holder. So this one would be hot all the time as long as the fuse is good and the ignition switch is on. On the flasher unit the "P" terminal is the one that is mostly central and lower on the flasher. This "P" terminal should have a Light Green wire on it. This wire goes to the Flasher Indicator Bulb on your dashboard. In my schmatic it shows that this light green wire changes to a light yellow wire inside the harness (God knows why) so at the dashboard Flasher Indicator Bulb you will see a light yellow wire but know this is the light green one from the flasher. The other side of the Flasher Indicator Bulb on the dashboard is a black ground wire that just goes to ground. So here's the way this deal works. The flasher will flash the green/brown wire going to the relay #1 terminal from the "L" terminal on the flasher and it will flash the light green wire going to the Flasher Indicator Bulb from the "P" terminal on the flasher, BUT.... it will only flash it if there is a load on the circuit. In other words one of the turn signals has to be turned on. The flasher sees the current going thru it because the bulbs are on and this causes the heating element in the flasher to start to flash.
IF YOUR FLASHER INDICATOR BULB IS FLASHING ALL THE TIME IRREGARDLESS OF THE POSITION OF THE TRAFFICATOR, then the flasher is shorted or the relay is shorted. Lift the wire off the "L" terminal of the flasher or the #1 terminal of the relay and see if your dashboard indicator bulb stops flashing. If it does then I would say that your relay is screwed up. It could have a slight short in it that is just enough to have a small current that the flasher feels it and starts to flash. Or the relay could have a contact stuck which is allowing some current/voltage to leak thru to one of the turnsignal bulbs and it is not hardly illuminating and you havn't noticed it. IF this is the case, then i think contacts 1,2 or 6 would be the culprits. Also make sure your brake lights are working as they should. IF something is irregular there it would indicated the problem to be in the relay. Here is a pic of the relay. You will notice that which ever winding at the bottom is energize by the trafficator, then that will pull the contacts to the left or right. The you can follow thru and see which terminals become energized. If the trafficator is in its central position meaning it is not turning anything on the looking at the drawing of the relay you will see that power for the brakes comes from the brake pressure switch terminal #5 and goes thru the closed contacts to terminal 7 & 3 which are the brake bulbs. If one of the relay winding gets energized from the trafficator, lets say the right side winding , then the contact breaks from the 12v brake switch circuit and makes contact with the flasher 12v power at terminal #1. Then terminal 3 which was the brake filament is now the flasher filament.
