John;
That's a good point-- electrical ground paths need to be well thought
out. Unfortunately if bonding straps are not used, electric current will
flow through whatever is the easiest and this may cause significant
damage to whatever is carrying the current. If the current is high
enough, it will spot-weld ball bearings (bearing balls to their races),
etc as well as cause other types of hidden damage. Welding can also
cause these problems if the ground clamp is carelessly placed.
It's fortunate you found that cable problem before you really needed it.

Hello John, did you determine why the cable failed ? I had a similar
situation a couple of years ago, the cable was (unintentionally) working
as a ground and absolutely seized the cable. Took me a while to figure
the cause of the failure. Good call to check/recheck the complete
system.

We have discussed checking our fire system lines and blowing them out
periodically to insure their being able to operate.
Here's another item to check. While dissembling the Hondaliner for paint
I
removed the bottle activation cables and discovered that one was frozen
solid.
I mean frozen so tight that it wouldn't move even when beating the
button as
hard as I could with my fist. Obviously this would have been a disaster
if I
had really needed it and hadn't check prior to putting it back on the
race
course.
The winter is a good time to check everything.
