Car won't shut off

You really should start a new thread. What specific alternator are you using? Model, make, like GM 12SI, or Toyota etc. Very first thing to do is find that out

Next what do you mean "confirm there's a .............." Who installed the alternator? No stock Mopar that is in the context which we deal with, has any of this. They are not used factory
Thanks, I'll start a new thread. I'm always apprehensive to do so, because I see folks commenting all the time with "there are a ton of threads about this," or "here we go again" type stuff.

It's getting late in the day for me, so it'll be a couple days before I can get the new thread started, beginning with the answers to the questions you've asked.

...and...mid-100s in Idaho?? I thought the mid-110s in the dry heat were bad! Thankfully, the rainy season has begun.
