just an idle question

 I presume on most bikes that have a battery and negative ground that the
main fuse, 10 amps or bigger, is always on the positive side, I guess to
help protect the battery from meltdown or explosion.  Never having seen
a bike with positive ground and not having paid attention to father's
old A40 Austin, I'm guessing that even negative ground systems have a
main fuse on the positive side.  Is this so?

(Maybe not a very important question, I admit, just something I keep
wondering about.)

No, positive ground systems put the fuse on the negative wire.

Thanks for answering the question he THOUGHT he was asking !!  ;-)

Thanks to Project Magnet, yes, but even if it makes me sound dumb, I was
really thinking that the fuse would be nearest the positive terminal in
both systems.  My reason had to do with what I take to be the actual
direction of current, as opposed to the so-called conventional
direction.  Perhaps it's simplistic but I reasoned that for protecting
components, it might be better to fuse them 'before', as it were, they
reach the current reaches them.  (Physics is not my talent, but liking
bikes, I can't avoid electrical theory.)

A fuse on the grounded + side of the circuit won't protect against short
circuits on the - side.
