    orkin noted in post #6 to check the linkage between the key and the switch itself. It is adjustable by sliding the switch a bit on its mounting screws. It could be as simple as the switch isn't going quite far enough to shut off the power.

    you've definitely nailed one of your problems as the coil should not be hot/live when you kill the motor! Glad you've figured some things out:)

    before i ruled the alt out, i'd put a voltmeter on there with motor running to see what you're getting at the battery (could be your volt gauge giving you probs).

    Do I need to drop the steering column to get to the switch?

    It should be visible looking under the dash without removing anything. It mounts to the steering column.

    Here is a column out of my 74 Nova looking down on it:

    And here are the two small screws going through slots on the switch bracket to allow the switch to be moved. (one is for a standard column and the other a tilt column but basically they both slide once the screws are loosened):

    Thanks for the column pictures. I lowered the column and found the switch. I removed it and using a small screwdriver it slides into all positions. I put the switch back on and was going to try to adjust it. I think I have something broken inside the steering column. When I turn the key it feels like something is jamming up inside the column and the rod that goes to the switch does not move. With the switch off I can move the rod by hand and the key does not move. If I have to tear into the column where should I start? Going into the column is uncharted waters for me. IMG_3959.jpg

    I've not had a column apart but I believe there is a rack made out of die cast material that the ignition switch tumbler assembly moves which then connects to the rod and then the rod to the switch on the topside of the column and maybe the rack or related gear is jamming up.

    I wonder too, if any column repair stuff is covered in any of the GM factory shop manuals ?.

    I would start another thread and see if anyone here has any info on tearing into a column but not sure which section to put it in.
