Mercedes A class always ON/OFF the right lump direction indicator
It's a wonder that some of the big mistakes are made by renowned manufacturers like Mercedes Benz. These are not banal mistakes already .....
A common problem with the A class is when the right-hand timer is switched on and when the left-hand switch is switched on, the right-hand flashes again. People convinced to give a direction indicator (if they do not pay attention visually to the board) can cause a traffic accident. Everyone thinks the problem is in the ablender. How does an ablender work? The signal transducer goes over one wire (in order to save one wire-incomprehensible) When the switch to direct plus 12V to the board in the solid state relay switches the output for the right shifter. When the switch turns on the left rectifier over the resistor, the voltage (voltage divider) drops to about 6V due to the resistor to the minus in the board, and then the solid state of the relay that kicks the left switch is turned on. So when everything is in the correct state, but what happens when the cold solder disconnects the resistors to the mass (found in the board) on the A16 pin, the 12v always comes to the left and right shifters because there is no longer a voltage divider. It's inconceivable to pack BSIa options in the board (ignition of lighters, lights ....) when the board is in the worst position in a car where the temperature reaches very high temperatures and produces a multitude of cold lumps. And in order to save one wire for a secure signal, two signals of different voltage levels (unstable signal) are being led .... They are questioning the lives of drivers and passengers https://www.youtube.com/watch?v=GpL4FTSmg5w |
