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.
That TRANSISTOR (if it is a 'real' ECU) IS NOT GROUNDED to the BOX.
Explain:
ALL "real" legitimate Mopar manufactured ECU's and ALL "real" old school replacement boxes such as NAPA Echlin or Standard Motor Products / Bluestreak used a REAL WORKING transistor which is NOT grounded to the box. That assembly you see, the transistor and the piece under it is the heat sink, is INSULATED from the box by means of mica insulation and sleeves in the screws.
THAT TRANSISTOR is CONNECTED to the COIL NEGATIVE terminal, which can have several hundred volts on it when in operation and which will SHOCK THE LIVING DAYLIGHTS out of you if you touch it when running.
FAKE transistors: Many? most? some? boxes imported from you-know-where use a DIFFERENT switching transistor which is actually INSIDE THE BOX and to make people "feel normal" they ACTUALLY INSTALLED a FAKE TRANSISTOR on the outside of the box. THOSE TRANSISTORS will not act as I said, and will in fact have the same voltage as the box, which, when PROPERLY GROUNDED will be ZERO VOLTS in reference to the firewall of the car
