Key will not kill the engine

[MrQuick]

yeah you can. I believe it should kill it when you disco the connecter or pull the bulb out of your alt port. Run it and pull the connecter, see if it works? Same effect as having the diode installed.

You can still wire your new altrnator but i don't have the info to do that right now.

I had the same problem when I hooked my starter solenoid up wrong, might take a look at that.

...what did you do with the yellow resister bypass wire? You should remove it out of the system completly.
