normally closed means the port between 1 and 2 is normally closed and the port 2 and 3 is open.Wolli wrote:it can´t be the valve. no power to the valve->closed. that´s the meaning of "normally closed". so it has to get some power, to switch to open. i allready had a very bad experience cause of the boost control, and it almost happened once again. so what is the real reason for that, spunkster?
solenoid gets power (12v) from a switch 12v and uses ecu PWM signal to control the valve.
the boost solenoid works between 10-90% duty cycle
