If there is no charging then its back to the alternator or the way its hooked up? did you recharge your flat battery with a mains charger after it went flat the first time? as no alternator will charge a battery from flat to fully charged,,,,even if you drove around the world none stop! the new alternator may have given up working becouse you overloaded the voltage regulator trying to recharge a flat battery witch would mean it was very week to start with?

3 weeks ago my car would not start, replaced battery and it has been fine till tonight and it would not start.


3 days on a new battery, yes it is significant. Four things can do this in a short time. alternator, starter, radio, and interior lights/ light switch. Alternator can be checked on the car, A sign for the starter is that it may drag or drag sometimes. Radio is lights staying on after the door is opened,Even the clock. Light switch is interior lights don't work or the dimmer switch doesn't work. These are just suggestions that I have run across. They still need to be checked. It can get costly.

We bought two new battery's a new alternator checked all fusible links from alternator to battery. Truck only runs for a few days with battery light on then we have to charge the battery. It's an 2004


open or shorted alternator circuit (control wire)
let your auto store test the alternator charging
on and off the truck.
inspect 3 wire connector for burn or lose connection
disconnect 3 pin wire and start the engine.if the light stay on you have shot to ground.

Why won't new alternator charge battery when car is running


Many cars have a voltage regulator that is integral to the alternator. Check to be sure it is properly connected. One year later afternoon the day before the Turkey was to be cooked I replaced the Alternator. I drove 200 hundred miles and had the car die at the gate to my destination. I failed to properly connect the Voltage Regulator on the Alternator. Look in that direction for a bad wire, fuse, connector.

Car won't start. Replaced battery. Ran 3 days. Now won't start


Quite possible the alternator is shot. If so, it will not charge the battery as you drive. Therefore the car is operating on battery power only.

Have alternator and battery tested. Hope this is helpful.

I replaced the alternator 8-13-09 car ran fine. would not turn over or start on 10-28-09 so got new battery. ran fine for 3-4 days. Did not drive car for about 2-3 days. tried to start car and would not...


Sounds like it's not charging. Get a volt meter on it, or have a garage check it out. The only other issue you may have is a draw from somewhere. (like a glove box door light staying on)

New fuses or new alternator?


Is the check engine light on? If so take it to a local parts shop like Advanced Auto call ahead to see if they have the machine to check the code, if the check engine light is not on then I would say that it is in fact the alternator.
