Ignition switch

Redfish -- thanks for all the test info., really good thread!

I have a possible ignition switch issue as well with my '71 Duster 340, in that after I drive the car for more than 15 minutes the steering column collar near the steering wheel key lock cylinder becomes warm to the touch.

The car has been in storage for about 3 months and I am ready to take it out of storage.

Where would you start with the diagnosis, and what's your best guess as to the cause? High resistance in the wiring?

Any help is appreciated.
