79' 318 ecu is live

That Transistor if it is real is always live. You can get shocked from them even mouted on the car. Sounds like the ECU is bad to me.
From what I've understood, if it is grounded properly, with ignition in run position it should not be live like it is. But ill swap it out from one on my duster then can purchase new for the duster if thats case.
