if i charge the battery it will run for a couple of hours until the battery is drained and it dies. if i take off the negative cable, it will keep running (with the charged battery), so the alternator must be fine. electrical components do not work quite right. the wiper blades are slow, if the battery is really drained, the stereo and heater fan wont work at the same time.
A couple of months ago the battery died and when i tried to boost it it wouldn't boost, so after deliberation i found out that both the battery and alternator were no good. so i replaced them. that night there were some rather large sparkes and electrical action when i connected the cables, and after ward the alt. fuses wer blown so i replaced them. i dont know if that has any thing to do with now.
its been really cold this week -20c and the fan belt has been squeeling mildly since this started

Follow your red lead off the battery and make sure it hasn't chaffed against something on it's run to the starter. Maybe it is shorting out.
I had a positive cable rubbing against the steering shaft, which ate through the rubber and started sparking.
It could also be that belt being loose. If you do the trick of pulling the negative cable, you should do it with the heat fan on high and the headlights on. Once you remove it, rev the engine a bit as well.

A alternator can! Drain your battery. in maximum situations it is not charging. yet I truthfully have considered alternators drain a battery over nighttime. Hook up a volt meter to it and start up the vehicle. you may get 14 volts. that's ordinary.in case you get 15 or greater volts. Or in case you don't get any volts it is undesirable. you additionally can load try the equipment basically via turning all your lights furnishings and a/c. in case you do no longer carry 14 volts it's time to alter. yet in some uncommon case's. I truthfully have considered a alt. Drain a battery whilst the vehicle is off. For some reason. After the vehicle is grew to become off. The alt needs to spin backwards drawing from the battery. All you may desire to attempt for that's hook up one factor amp meter to the huge fee cord at the back of the alt and the different to the feed cord. in case you prepare any amps. it is drawing. the comparable would be completed with a starter as we are going to. over the final 35 years as a tech. I truthfully have considered the two. So the respond is confident!..

DId you hook the battery up backwards? If you have sparks when connecting the negative cable to battery with positive cable hooked up then you have a short circuit somewhere. Don't pull the cable off with engine running to check for charge. Hold a pocket screwdriver or something metal to back of alternator (center where the bearing is) to check for magnetic field(pull) this indicates alternator is charging if the charge gets to the battery is a different problem. Include year of vehicle and specs next time.

sounds like you might have a positive wire touching something metal. You might have an exposed positive wire on the starter or solenoid and that wire is grounding out on a piece of the metal undercarriage. You need to disconnect your negative cable and start feeling around with your hands and try to find a wire, around the engine, that has some of the outer insulation worn off.
Really search the engine compartment and the dashboard.
You can also use a test-light.
[ The test light is simply an electric lamp connected with one or two insulated wire leads. Often, it takes the form of a screwdriver with the lamp connected between the tip of the screwdriver and a single lead that projects out the back of the screwdriver. By connecting the flying lead to an earth (ground) reference and touching the screwdriver tip to various points in the circuit, the presence or absence of voltage at each point can be determined and simple faults detected and traced to their root cause ][wikipedia]
Be careful, though, you could set-off your airbag withe test light if you go poking around the steering column.
I think you might be able to use the test light to determine if you are grounding out by disconnecting the negative cable from the batter, leaving the positive cable on, then touch the test light to the negative terminal of the batter and then touch the negative cable connector. If the light come on of the test light, then you have an 'open circuit', that means you have a postivie wire touching something metal. Or it means your dome light is on or your hood light is on, be sure those are off when you do the test by the way.
anyway, good luck and if I'm wrong on using the test light, you might try asking the question here on Yahoo! Answers , "how to use a test light to find a ground fault"

Sounds like HOT [very well charged battery [when it sparked!] what seems to be wrong is poor cable(s) or MOST LIKELY just not properly connected terminals or not clean or both. Bend cable about every 2" to 3" to check for "solid" spot [corrosion] and if found--replace cable. Terminals: remove and
clean [coca-cola and then battery tool from auto supply -- cheap]. Are bolts & nuts seviceable? Now terminals ON THE BATTERY: Clean 'em . stop, Are
these the screw in type? Aha - the bolt going in and all those lousy General Motors connections must be perfect and the bolt MUST screw in like your working on an oil derrick! [really, 4 a battery, these are really tight!!]. Some people prefer to take battery out and to shop for a check and charge after disconnecting. when reattaching: PUT THE CORRECT CABLE ON THE CORRECT TERMINAL! PUT THE HOT(red) ON FIRST -- THEN THE GROUND (blk).

Hum,
I'm not sure but you may want to have this checked by a repair shop, they may print a complete electronic wiring diagram and need about a day or two to visually inspect everything in regards to this trouble. You may want to aske about the "voltage regulator-(if it has one)...
...I hope this helps. by the way, What's the year and model of this JEEP?
Best wishes

You need to stop trying to fix stuff you don't have a clue about and take it to a garage.
There is obviously a very serious issue with your electrical system and they're just going to have to go through it and trouble shoot it.

maybe you got the wrong alternator or there is some bad wiring in it, make sure your belt is tight.
if your check engine light is on take it to a auto zone and they will check it for free
