Yep


38 years in the business and I never saw anything like that.

Way back a million years ago I put the battery in my 53 Chevy backwards
but the generator just repolarized.

The ammeter read backwards and the gas gauge pegged negatively
but nothing was harmed

What a bunch of youngsters. ;-)
Back in 1963, my dad had a TV repair shop.
He did some work for a car repair shop.
One day he fixed the blown output transistor on a car radio.
This was when car radios still had tubes, but they had switched
to one transistor in the audio output.
Car guy bought it back...It's broke.
Fixed it again.
Car guy brought it back...IT'S BROKE!!!
Fixed it again.
This time Dad and I went over to the shop and
measured the battery. Was charged backwards.



Very interesting


BTW: My '53 Chevy (3100 truck) had a radio that must have been put in
later. It ran off a vibrator and reversed battery polarity did not matter
