Block heater problem

[hern]

The block heater on my 97 doesn't appear to be working. I have electical power to the heater cord. I am a little afraid to use my test light on the cord going to the heater. I can't find any info on the block heater in any of the books I have. Notta! I think it is probably the cord due to fact that in spots the covering protecting the cord is brittle. 210,000 miles. Does anybody know if I can just change to cord out, or how to check it (the cord ) to see if it is the problem? Any info would be appreciated. I'm to old and fat to be walking.

I am not a tech but this is what I would:

With 110v I wouldnt use a test light...I would test with a multi-meter (set for 120 AC...Check voltage and continuity..and I know on 6.0 (but with a 7.3 I am not sure) the cord itself is replacable.

Any techs wanna chime in here?

Never mind. It simply unplugs.

Yes you can replace it however I think Ford wants like $30 for the thing but the plug they use is a universal I believe at least it was on my 94. Went to the local auto parts store and bought a cheap block heater for $15 and used the cord from it.
