My 73 K20 with a 350 wont shut off with the key all the sudden. Had the truck about 6 weeks and had not had the issue previously. I just added a second battery, they are wired in parallel with no isolator. I also changed out a fuel sending unit that was not working, not that I think this has anything to do with it but want to give as much info as possible on what has recently been done prior to it starting this.
Truck starts fine, seems to be running fine. When the key is turned off the engine keeps right on and doesn't miss a beat. I can take the key out. When they key is off with engine running the blinkers are off and not getting power, as soon as I turn the key back on the blinkers have power and work. I unhooked the second battery and made sure everything was hooked back up to a single as it was before it started doing this, no change. I replaced the ignition switch today and still doing it.
I cant help but wonder if the recent battery work did something, seems like to big of a coincidence for this to have magically started this right after I was replacing stuff.
Any ideas on what to check next or other threads that deal with this would be greatly appreciated.
