I addressed something along these lines a little while ago.  Perhaps it
was burried in my message and most did not read it (ah well).

When I did maintenance on my ET, I found 2 things that might relate to
your problem:
(1) One heavy gauge wire had gotten loose and was being rubbed by the
drive belt.  This wore down the insulation and it may have touched
tractor body on a few occassions.  I think (although I have not
confirmed this) that this wire touching tractor body may have resulted
in the terminal of Battery #3 melting.
(2) In the access panel beneath the main console, I found a medium gauge
wire that was crunched by the steering gear.  Right near that area is a
large, flat metal plate being used as a shunt between wires.  I noticed
the corner of this metal plate was scorched and somewhat melted. 
Perhaps this wire being exposed and contacting the metal plate caused
that.
