A year or so ago I put the battery in backwards (reversed polarity) in a 215
Buick powered vehicle.
What a mess that made.
It has a battery disconnect switch, which was off. I accidently put the
battery in backwards, tried to start it and nothing happened as the battery
disconnect switch had been left turned off. So, with the ignition key still in
the on position, I turned on the battery disconnect switch.
Smoke, burned wiring, ruined alternator, melted ampmeter, etc. Took me quite
sometime to rewire the thing.
I have now gone to great lenghts to mark plus and minus in such a way that no
idiot (meaning me) will ever put the battery in backwards again.
Regards,
J. B.
