Summary of change:
2006.04.24 I was trying/testing idle-channel output using two different channels. Useing Step A "output" was always on (0% TSP of course) even before I started trigger-signal.. Useing SPECFET1 I never got any output (selected in MT), and it is mounted. Beware that flyback diode is needed for specfet when driving inductive load like a solenoid! - Yes was just testing with scope.. Connect a diode (like 1n4007 or BY399 or ES2J or similar) * anode to switched point of the solenoid (channel output, EC18-pin..) * cathode (marked with a line) to the other pad of the solenoid: the same where you connect the positive +12V (switched and fused) power '''Q:''' What output channel is recommend fore idle-valve (2-pin VDO-valve)? http://www.vems.hu/files/HansK/P6220090.JPG * a free injector channel is most common * or a stepper output because these have onboard flyback by default. - Okay I'll just stik to the stepper-output, mount a injector-fet next time the box is out.. thanks
