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.

The first thing I would do is inspect the harness connecter. There are 2 connecters exiting the column . The one from signal switch has smaller wires.
Copper is an exellent heat conducter so if the ignition switch is heating up its connecter should get warm too. I've seen those connecters melted so bad that the switch side has to be destroyed to get the 2 apart. Lets hope the cars harness side isn't damaged beyong reuse.
That igntion switch isn't as hard to replace as it is just annoying. They used 73736 different types of hardware in there so half the tool box is required. LOL
I must repeat a warning about aftermarket switches out there. Many of them have a extra (WRONG) wire in them. Hook it up directly from the package and you'll blow the dash light fuse.
