Yea. I've been thinking that too. We tested the ground to the engine and
found it a little weak, but I don't think it was THAT weak. I'll be checking
the ground path again later today.

The point for others is that it's surprisingly EZ to damage an
"indestructible" hose with amps and get an intermittent leak that's hard to
find and could REALLY spoil you're day. A LongEZ driver (friend of Buly's)
from near here crashed & burned recently with an engine fire (Rotax engine).
That's what made me extra extra cautious.
