[Healeys] Jump starting, a final note

[Editorgary at aol.com]

Just remember when jump-starting from one vehicle to another: Never, ever 
make the last contact to a battery post. Make your last connection the one 
that might go to the post on the dead car that would go to the chassis (posi 
if posi ground car, negative if negative ground car). Our batteries generally 
are old-school enough so that they can build up explosive vapors above the 
battery which can be detonated if the contact sparks when it touches the 
post. Boom!

Generally, positive to postive, negative to ground on neg ground cars; 
negative to negative, positive to ground on posi ground cars.

But, since emergency batteries with fail-safe circuits have gotten so cheap 
and useful in the past few years -- mine has an air compresser and 
emergency light -- you should just keep one of those in your garage.

Good luck,
Gary
