Help - parking lights will not go out

Not 100% sure, but I suspect unburned fuel would collect in the exhaust
system
and would likely damage the cat when it burned.

If I remember correctly, the cars with the generators could be started
in this manner as there was enough residual magnetism in the field to
start generating a current. Alternators depend upon an external current
source to energize the field suffienciently for this to work. Maybe
alternators with field magnets instead of coils could be "bumb" started.

What is "bump" starting? I've heard of "push start" but not "bump". A
"bump" start had got to be hard on a manual tranny in any gear! Even
when "push" starting a manual you should start in 2nd.

"Bump" start reminds me of the old joke about the gal that heard you
had to be doing 35 mph before you could start an automatic. She got
up to 35 before coming in contact with her hubby's car! ;-)

This might explain why car *without* a battery (or at least functionally so)
might not be successfully push-started. But usually a battery that's too
dead to start the engine still has enough juice to run the fields in an
alternator. And it doesn't explain why one should *never* attempt to
bump-start a newer car. That admonition seems to imply some sort of damage
that is likely to occur.

I'm still curious as to what that reason might actually be. I've forwarded
the "NEVER NEVER bump start" message to an automotively-knowledgeable
acquaintance, but he hasn't yet replied. And he's been having computer
problems, so he might not *ever* reply. If I think of it, I'll ask him in
person when I see him later this week.
