"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)."

What happens when you charge a car battery on the wrong polarity?
You can't recharge it hooked up in reverse. You will destroy the battery or the charger if you try it.
What is reverse polarity protection?
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.

Where can you find the exact location of a fusible link on a 1987 mercury grand marquis They hooked the jumper cables upbackwards and it cranks but will no start replaced battery and starter any idea?
Have the ECM, alternator and any other electronic components tested. Reverse polarity can destroy solid state components instantly and you may have some serious electronic damage.
What are the car battery cables hooked up to?
the alternator
What is reverse polarity-?
Reverse polarity is the opposite of normal polarity. Normal polarity in electronics is when you have the positive hooked up to the positive terminal and the negative to the negative terminal. Reverse polarity would be having the positive hooked up to the negative terminal and the negative to the positive terminal. The same concept can be used with magnets.
Why does battery go dead when hooked up but alternator is good in geo metro?
check your battery ground and your alternator ground
Why computer has no light?
If it is otherwise running, you have probably hooked the leads backwards. The panel lights on computers are light emitting diodes and they will only light up when hooked with the correct polarity.
Is the battery connected to the alternator?
Indirectly. The positive cable on the battery is hooked to the starter. The other wire on the starter post goes up to the alternator.
Replaced a battery and hooked it up backwards it sparked and then hooked it up the proper way and the car started the next morning the battery was dead bought a new battery same thing happened help?
You hooked up the batteries in Series whch pumped allot of current thur the circuit..which probably fried the voltage regulator and probably blew the diodes on your alternator. you can have the alternator tested at an auto parts store.. but I'd replace the voltage regulator ( if its not part of the alternator ) along wth the alternator.. gpawlak1@rochester.rr.com
You have no lights but you have a new battery and a new alternator what could be wrong?
Recheck your battery to see if hooked up right.
1996 VW jetta gl it runs fine without the alternator hooked up but as soon as you hook it up it stalls and shuts off Any suggestions?
Can you turn the shaft of the alternator by hand? Is it the original alternator? With the given information i would say that the alternator is in need of replacement.
