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
compliment.
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
filler.
