Bad Puppy post mortem

Interesting.  I was just fiddling with the blower motor on the V8.  I
had the cooling hose removed and was spraying WD40 in there.  I also
pushed down on the brush tower, a little too much it turned out.  This
caused the blower motor to stop and there was some sparking and smoke.
I turned off the ignition and corrected my "adjustment" and it was
fine, and is running very well now as a matter of fact.  Anyway, I
wonder if your blower motor had been recently treated in a similar
manner or if it could have just built up enough crud to cause a
similar problem without any help.
