give or take 2-4 hundred dollars. alternators are not cheap with newer cars. check the web part stores for the best price on the part and ask the mechanic shop to meet the price, or if they will put it in, if you bring the part. It is not a difficult fix if you want to do it yourself. send an e-mail if you want the specific information on the how to. ish4031eagle@aol.com. hope it helps. duboff
Charge it, replace it,test the alternator,Charge it, replace it,test the alternator,
Simple, just replace your alternator..
Was quoted $500 to replace the Alternator and battery yesterday (May 2009) which seems a little high (they wanted $100 for the battery and $20 to put it in so you can assume $380 parts and labour for the alternator I guess)
Replace Alternator
Repair the alternator to battery connections or replace the battery.
Yes, if the voltage level is too low to start the car.
If your battery was dead and you jumped it to get it started and the gauge shows your not charging you need to replace the alternator.
It is most likely a bad diode in the alternator that is causing both lights to stay on. Or its just your alternator going out, replace alternator, and check pads an rotors.
Any alternator will charge at idle.
Three things to look for: (1) A loose belt will not spin the alternator fast enough to fully recharge the battery - tighten and/or replace the belt; (2) A bad or weak alternator will either not provide enough charge, or any charge at all to the battery - have the alternator checked out and replace if necessary; (3) a battery with a dead cell will not hold a charge and will "die" quickly - have the battery checked out and replace if necessary.
I have a 2.0 1995 Mercury mystique the battery charge light was on no output on old alternator. Replaced alternator No output from new alternator "charge light out" (wiggle test wires& re-check wires) at alternator *still no output* is there a fuse that could be the problem or just another bad alternator... I would check the alternator plug before getting another alternator, it may be bad. And is a lot cheaper to replace.
Check fuses first. If fuses are good, check the voltage from the negative battery cable to where the wire bolts onto the back of the alternator. (With the engine running). If you can't reach the back of the alternator, then measure across the posts of the battery. Voltage should be about 14 volts DC. If lower than that, replace the alternator. When you replace an alternator, it's a good idea to replace the battery, as a precaution.
