bad alternator ? its not charging the battery
check the alternator
My alternator stopped recharging my battery but I can't take the tension off my serpentine belt to put my alternator back on.
yes if the alternator isnt charging the battery correctly then it couldnt be sending ecu false signals when my alternator was playing up , my central locking my hazards interior light and rear wiper stopped working
Check for poor ground connection either at the alternator or follow the negative cable coming from the battery.
Either your battery is dead and wont accept a charge or your alternator has stopped charging the battery due to a blown fuse, loose or damaged wiring, loose or broken drive belt or the alternator itself has gone bad.
There is a good chance that your alternator has stopped working. It could also be just a loose wire from the alternator to the battery that is not letting the battery charge. Also it could be a bad battery. When a cell in a battery dies it will hold a charge for a short period of time but then rapidly die. Get the battery checked first. they the wires, then the alternator.
I just went through this with my Windstar - stopped by my favorite Autozone and they did a pretty thorough electrical test, including the alternator and battery. Most of the auto parts stores offer free testing. Easiest thing to do is remove the positive connection to your battery if you Freestar stalls....Alternator is no good(just happened to me)
If your 2001 Jeep Commander randomly stopped working and won't turn on, you likely have one of two problems. Your battery is dead, or your alternator is dead.
