Not unless you want to blow something in the electronics up...
All batteries have two terminals, one positive and one negative, and usually they need to be hooked up right for the equipment to work. Some equipment will be damaged if you hook the battery up the wrong way - reverse polarity. Equipment that has reverse polarity protection has something in them which makes them able to stand being hooked up wrong w/o being damaged.
the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet. switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.

Discharging it to 0V (ie. absolutely empty). And not battery, but "cell" (even a small AA or AAA battery is consider a "cell" - think Duracell).Batteries are usually made up of individual cells (like car batteries, RC batteries etc.), and even if not all of them are discharged completely, if even just one cell reverses polarity, it will do irreversible damage to the battery.
What is meant by polarity? Answer An electric charge has a polarity of either positive or negative. Also a voltage has a polarity, in that it could be positive or negative, with respect to some other voltage, such as the one at the other end of a battery or electric circuit.
There is only one starter per truck. If you follow the positive battery cable from the battery it will lead to the starter.
any special battery
a 127 should do the job,Wouldnt recommend a truck battery
A: Depends on meter leads voltage polarity and the diode itself orientation to these polarity. One way is should show a low impedance + to anode Reverse the diode it should be hi impedance
You will be able to find out the polarities of the windings. You can just put a digital meter on one winding and then touch the battery to the other side to see which polarity it has.
"If you connected the battery in reverse that will certainly fry the alternator and cause damage to any other polarity sensitive components as well. The alternator is NOT suposed to spark, it charges by by generating alternating current which is converted to direct current through a diode pack known as the rectifier, and the voltage is regulated by some more electronic wizardry called (amazingly enough) a regulator. Normally when alternators go wrong the charging warning light will glow, and you will get the wrong readings from your voltmeter (if your car has one)."
In a normal distribution system, one wire is always connected to earth. Reverse polarity occurs when the live and neutral conductors on a system become reversed or 'swapped over'. It's a very dangerous situation with serious safety implications.
