Re: [Chrysler300] 300G electrical problem

Obviously, you have current back-feeding the coil.

With the key off, a test light @ the coil will prove this. Then start going back along the Ignition wire to find out what has shorted into the circuit.

Start with checking the coil for voltage with the key off. then since you just replaced the switch. go to the plug and unplug it and see if the voltage went away.

If so, then it's either the electrical part of the switch or something it feeds.

When the switch is in run, it supplies current to the coil and other things. with it off, that current source is cut.
But if somewhere in the circuit, something it feeds on the Run circuit, like a relay is not turning off with the switch and has current going back into that branch of wires to feed the coil.

Just a thought, unplug the windshield wiper motor and see if that solves it.

Started car a couple of days ago, ran until warm and turned key off.  Engine continued running with key in any position - on, off, accessory.  Not simple dieseling or run-on.  Only way to stop is by turning key to off, holding brake and putting in drive or getting out and pulling coil wire off.  Replaced ignition switch to no avail.  Any group thoughts as to problem and cure  ??  Any help will be greatly appreciated.  I'm no expert with auto electrical.

Side note:  NAPA was closed so I bought the ignition switch @ Advantage Auto for $4 less and swapped out the tumbler.
