With that said, when the injector isn't being turned on, you would see the 12 V on both leads of the injector. The supply side is obviously 12 V and also on the other because the injector has a fairly low resistance, and the EC-2 lead is not pulling it to ground (open). I hope that makes some sense. Maybe someone else can explain it better.

Tonight I spent some time checking around the engine. With both inj. switches on, I have 12V on all the wires going to the injectors? As far as I know, there is one 12V feed from the switch to each P/S injectors and one wire for each injector comming from the EC2 providing intermitten ground. If I'm right, how come there is the same voltage on all the wires? Buly BTW few months ago the engine was running perfect? I have no idea what caused all this trouble? -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net/lists/flyrotary/
