Hey guys..
im helping a mate repair and restore his 1990 mx5 miata of which he has a motor controlled exhaust valve that opens and closes by swapping polarity, this used to be controlled by a box and a reciever however this box broke and now no longer is available to be used.. at the moment i have the exhaust connected to a dpdt momentary switch however he wants to integrate a single momentary push button to control the opening and closing of the valve..
basically the need is - a single momentary push button to reverse the polarity of the motor however the circuit must be capable of 15A at 12V and must also not output anything when the button is not pressed
So basically push button (outputs 12v and GND) release button (No Positive output) Push button (outputs GND and 12v (Reverse Polarity))
Also Circuit will be installed in a car so it should be capable of up to 14.4V
Anyone got any ideas??
