ignition lock

[40cpe]

I would remove all the wires from the ign. terminal on the switch and check for the terminal on the switch to be hot with the key in the "off" position. If the terminal is hot, you have a switch problem. If not, you are getting back feed from somewhere that is powering your ignition. If there are other wires on the same terminal, check to see if any of those are hot with the ignition off.
