OK, one of movie below is when engine is off, second one is when engine is on. Led strip is connected to battery negative and to +12v in turn light. Lights in car are controled by module, without relay. When I connect positive wire directly to battery positive pin, it is working fine. Problem is...
OK, I will play with it... I don't have a workshop power supply to test it so I hope it will work without fire ;)
In fact, I have one more idea to separate it directly from the canbus powered line via a relay. I have a semiconductor relay DD2203HK in stock. I was thinking of using it...
OK, I will try to expalne better:
I have DC current, pulsating from 0 to 12v (square wave). I need to stabilize this current to get DC current without pulsating (12+ still, high). I wanted to use the LM7812 type stabilizer with the appropriate capacitors. Question: what and where to use...
I have a car with canbus. When the engine is off, the voltage graph is constant. When the motor is on, the voltage is alternating (peaks). I have a led light controller that works fine when the engine is not running. When I turn on the car, the controller stops working properly. How to make...
