hey, my car died the other day. :x when i tried to start it, i could hear the starter clicking, and the alternator was trying to turn, but it seemed like the battery just didnt have enough gumption to get the thing started.
My buddy and I did manage to get it jumped (he has a pathfinder...that thing can jump anything) , and it started up for the rest of the night, but when i tried it the next morning, i had to fight with it to get it to start. That night, afterwork, i had to have it jumped again.
why isnt the alternator charging my battery? is it just too dead? if it is being charged, what could be draining the power?
thanks for any infon you guys can give me

Sounds to me like your battery kicked the bucket. To test this, get yourself a multimeter and hook it up to your battery. With the car just sitting there not running, take a reading of the battery voltage. It sould be somewhere between 12v and 13v. Start the car. When running at idle, the alternator should be charging the battery 2v -3v above battery voltage. Now turn on everything electrical in the car at once, high beams, stereo, heater blower on full, interior lights, wipers, etc. Check the voltage at the battery again. It should still be about 2v - 3v above the inital reading you took. If the voltage does not rise about 2-3v for either of these, it's your alternator. If you get a voltage rise of 2-3v for each test it's your battery.
Check to make sure that the battery cables are good and tight to the terminal posts as well. Also, if there is provision to check the water level in the battery do so. The plates should be completely covered with electrolyte. If you cant see any water at all in the battery, or it looks like there's "fuzzy" stuff on or around the plates, get a new battery. If it checks out, and the fluid is just low, top up the battery with distilled water. (caution, this is sulphuric acid. avoid splashing and take safety precautions as required, ie glasses etc)

The average life span of a battery is 3-5yrs, so if your batter is in the range or older, it's a good sign you'll be needing a battery.

First off, alternaters are supposed to float a battery, not charge it. That is why they make battery chargers. Charge your battery overnight. And try to start it. If it starts, you are good. If a jump got your Escort started, it isn't the starter. Stop by Autozone and have them check the battery. They they will check the Alternater. Odds are, if your battery is good, the engine will run off the battery untill it is dead. Easy test is start your car, remove the hot wire off the battery, if it runns, the battery is dead. If it dies, the alternater is bad.

Please don't buy a rebuilt alternator at AutoZone or Pep Boys, etc. You'll be sorry!

And how old is your battery and how long is it rated for. If it's past it's expiratin date (I forget exactly what it's called) then plan on getting a new one.

Pep Boys and AutoZone batteries are OK though, just don't buy an alternator there!

sweet...thanks.
the only reason i mentioned the starter is because my boss had a scort and his starter (so he says) wouldnt disengage and was draining the battery. any truth to this?
