Having problems with your 2003 Ford Taurus ?

2003 Ford Taurus, Replaced alternator 3 x, replaced battery 2x, ABS Light, Battery Light, Airbag Light, Brake light all come on, car does not show RPM's when this happens and eventually will not show speed either. Once stopped and turn car off, cannot restart. Same symptoms that lead the replacement of the Alternator. What's wrong with my car? Techs say either alternator again or computer. Alternator tested low at 12. Whatever that means.

WELL CHECK ALTERNATOR FUSE.IF FUSE GOOD HAVE CAR SCANNED FOR A GENERATOR FAULT CODE.YOUR ALTERNATOR IS PCM CONTROL.WITH CAR RUNNING YOUR VOLTAGE OUT PUT AT BATTERY FROM ALTERNATOR SHOULD BE 13.5 TO 14.5 VOLTS.CHECK BATTERY CABLES MAKE SURE THEY ARE CLEAN AND FREE FROM CORROSION.
Electical problems can be elusive. if the alternator output is 12 volts on a brand new unit, then i would suspect wiring, connectors or fuses. especially after replacing the alternator 3x. consult the owners manual for fuse location. the fuse for the alternator. should be located in the engine compaartment in the power distrbution box. open the box and look at the fuses, puling out one at a time. the bad one will be obvious as the element will be burnt. i would guess it is a large 30 amp maxi-fuse green in color. if all the fuses a good. you'l have to check connector and wire continuity. best left to a tech.

I have a 1996 Ford Contour GL with a 2.5 L V-6. The battery light came on before and i replaced the alternator twice so far and the light has stayed off. The battery is in good working condition. It doesnt have a bad cell, the water level is fine and it will hold a charge. But after i start the car, the car will run fine either, (A)as long as the battery is hooked to the jumper box or (B) until the battery runs completely dry and the car runs dead. This is the 4th alternator altogether, the 2nd

I replaced the alternator in my 2002 gt Mustang and the battery light came on drove the car for around 20-25 miles and it died. I tried to start the car and all I got was a ticking sound.

I connected my battery wrong. I did not start the car I knew what I did as soon as I did it. When I corrected the problem I noticed I blew out the radio, so I changed the fuse. My charging light came on so I replaced my alternator. I started my car but my battery still won't hold a charge and the car shuts off within a few minutes. Is there another fuse I blew that prevents the alternator from charging the battery.

My alternator went bad on my 2000 hyundai elantra and left us stranded at a stoplight. We had to be pushed off of the road. I replaced the alternator with a brand new one and it hasn't been on the car for 2 weeks yet and my car did the same thing again. The alternator tested bad again. I don't know if there could be something wrong with the wiring system in this car or what but it's aggrevating. Also, I can't get the check engine light to go off either.

I have replaced the battery and alternator and the battery light is still on. I have cleaned the cables, I have replaced the bolts at the battery posts, I have spliced off the end conecting wire at the alternator and it still won't hold a charge for more than a couple of days.

I got a new battery when my car completelty died after having trouble being stuck in some mud. The battery light was still on and my mechanic told me I more than likely needed a new alternator. So on the way to get the alternator my car died again. I got a new alternator and put that on but my car still hardly made it home.

I have a 1997 Plymouth Grand Voyager. We just replaced the battery and the alternator. The battery and check engine lights are both on and the battery isn't charging correctly. It checks at 12.5 when running at the battery terminals, but should be between 13-15. The car kicks a little shifting from 2-3rd gear, and it has codes p0700 and p0740 showing.

97 Escort that failed to start a couple times-obviously not enough from the battery. Had it tested at a parts store they said replace battery which I did. Started car and "battery" light is on in dash. Had the guy check and he said there is 0 volts reading form the alternator. I would figure a bad alt should at least show a few volts?? I cant seem to find a fuse or bad wire yet there may be. Also how do I check alt directly for voltage?? Thanks so much. Wayne


You should be able to to check for voltage directly at the the largest of the wires going to the alternator[black with an orange tracer].If you have no power then you have a blown fusible link,from the starter solenoid to the positive battery post.]I ... 1997 Ford Escort

Alternator went out and killed the battery. Replaced the alternator and car ran fine for a day. The battery charge light came on and stays on constantly. Also, the fuel gauge does not move. I have checked all fuses and replaced a couple of blown ones. Alternator is working fine (cranked car, removed positive cable from battery, car continues to run). Out of ideas.


I cannot access the wiring diagram, but one of the wires from the alternator usually goes to the dash light. It may go through the computer or other circuitry on the way. If you can trace that wire, you may find the problem. Sorry I can't tell you ... 1996 Mazda MX-5 Miata
