Did I say 14?  I guess I did.  I meant 18.  And it's stranded, with some 
strands probably missing.  Too big?  Probably.  I just got tired of the
fuse failing when it was -20 below.  That's when the current is highest,
and that's when the fuse is needed the most to be conducting.   

Call me a hillbilly, if you wish.  Coming from you, that's probably a 

There's also common sense. If you turn on the glowplugs, and the lights
go out on the car, you have a problem.  Shorted glowplug (never seen it),
or perhaps a low (or cold) battery.  The low battery is the one I am the
most experienced with.  

I've just gotten stranded too many times out in the boonies with out
a spare germanfusenlittlestrippenofpotentiallymeltenmetal.

The truth is that the stranded copper wire was an upgrade from the 
field fix, which was to put both wire lugs onto the same screw.  Good
thing I had a #2 phillips on hand!


ps: Landed last week at "French Lick, IN" (KFRK).  That's almost hillbilly.
The guy who fueled me was real nice, and his 4 year old daughter was
cute and airplane savvy.  He said that he saw a Caravan with the outboard
right wing, from the strut outboard land one day (CVG).  The pilot
didn't even know he lost part of a wing on a telephone pole, and said it
flew fine.  That's robustness.  Now if I could wack a Jetta on a phone
pole and still fly it home, I'd be doing great.  At least it already burns
JET-A sumpings.  Picked up a JET FUEL ONLY window placcard at Bradford PA
airport.  I jsut haven't had the guts to stick it on the window by the
