This has recently happened to my 1996 Camaro after sitting idle for several years with a brand new battery (installed it to move the car to my new house). Knowing the battery would be dead, I took it in to be charged and the parts store accused me of trying to jump with the wires crossed. My other cars are a Prius and a Volvo. Anyone who knows those cars knows why I would not have attempted to jump a Camaro. Nevermind that the car was/is parked head-in inside my shop.
Anyway, I bought a new battery, hooked it up, turned the key on and the gauges pegged then, when I tried to start it, the battery posts began to smoke. Battery people have said it is possible to take a new battery and drain it to the end of its "useful" life (not a pun, as in the batter is no longer useful) which can reverse the polarity. Of course, a 1996 doesn't have a generator so it doesn't need arching but, clearly something is amiss!
I'll try and repost once I hear back from the mechanic.

What would cause a battery on a forklift to explode?
Overcharging by the alternator or if it is connected in reverse polarity.
What would go bad if you wired an alternator reverse polarity?
You would probably toast the diodes in the alternator.
Would reverse polarity cause equipment to run even if switch is off?
The case of reverse polarity would only happen on a DC system. As to would it cause equipment to run when switched off, no, if the switch opens the equipment's power supply completely the device will not operate.
If you reverse polarity on the battery and the fuses are fine and the alternator check out ok why would an 81 Toyota pick-up wont stay on whithout having your foot on the gas pedal?
When the truck is idling at low RPM, the charge supplied by alternator is not sufficient to run truck and charge battery of reverse polarity. Alternator expends majority of amperage toward charging (which never takes) and increase in RPM is required to spin alternator fast enough to accomodate ignition system and charging system in unison.

Is the LM3914 IC protected against reverse polarity?
i would never naturally assume any circuitry to be "reverse polarity" by default even if they are. since this can fry a lot of IC, and micro controllers. there are several options to adding a reverse polarity protection circuit to your project you can find three easy to implement circuits here: http://provideyourown.com/2012/reverse-polarity-protection-circuits/
What happens to the load if reverse the polarity of diode?
if you reverse the diode in a half wave rectifier, you would expect the A- Ripple to increase B- output to be less filtered C- out put polarity to be reversed D- output voltage to decrease
How do you reverse polarity natural magnet?
Demagnetize it, then remagnetize it the opposite direction. It's a lot of work and it would undoubtedly be easier just to repaint it and claim you reversed the polarity.
What is reverse magnetic polarity?
lets say the earth was to have a magnetic polarity reversal the north pole would become the south pole, and the south pole would become the north pole. i hope that helps.
Which is an example of reverse polarity?
Reverse polarity means that the direction of an energy flow is opposite of normal. In house wiring, it would mean that the hot wire (in the US, the black wire) was crossed with theneutral wire (in the US, white wire). Appliances would still function, but the flow of current is reversed (and unsafe)
Why would cause the 1995 Nissan Pathfinder not to go in forward or reverse?
What would cause the 1995 Nissan Pathfinder not to go in forward or reverse?
How would reduce the reverse polarity in magnetization of permanent magnet?
Degauss it and remagnetize it in a field. Best when heated over the magnets Currie point. Cooling it down in a field the reverse of what you started with.
Will a bad alternator cause new spark plugs to smoke?
Spark plugs don't smoke. A bad alternator would cause a dead battery.
