Gosh, an Amp Gage, ain't seen one of those since my Grandma's '63 Plymouth wagon.
And I got a butt whipping, because when the battery went dead, I piped up from the back seat (10 YO at the time) that the funny gauge on the dash has been pointing to the left all day.
And my Dad said why didn't I say something sooner!
Right . . . , the 10 YO kid in the back seat is tasked with watching the Amp gauge while a grownup is driving the car . . .
