Check the fuel filter if the cars battery and alternator is good it might be the lack of fuel that is bogging the car down. My advice to you would be to check or replace the fuel filter.
The alternator or a poor wiring connection.
Have airbag checked. Codes can only be "pulled" when the warninglight is illuminated.
If the light comes on and its an auto tranny you need may need a new alternator. i had the same problem. the alternator was drawing power from my battery and o i didnt have enough power for my auto tranny
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alt belt.Also check that the belt is routed correctly - I found a wrong way to route the belt and had similar symptoms.See "Related Questions" below for routing diagram sources
If it flashes red it means it has low battery, if it flashes green it means the battery is okay!
What does it mean when the airbag light and battery light on 1999 Ford Escort flashes?
voltage regulator, sometimes its in the alternators, advance auto parts doesn't replace them in remanufactored ones.
Generally when your light is flashing it is indicating that your battery is not charging properly. It usually means that your battery, alternator or alternator belt need replacing or adjusting. Easiest thing to check is your belt so you can start there, make sure it is not loose or frayed. Next, disconnect the battery terminal while your car is running, the alternator alone should be able to keep your car going. If the car DOESN'T stall then it is most likely that your battery that is no good. If the car DOES stall then your alternator is defective. To properly test your alternator with a voltage meter attach the ground to (+) positive probe to the main power feed on the alternator and attach the (-) negative probe to the (-) negative battery terminal or ground it on a piece of the car's frame. It should read somewhere around 10.0 - 15.0 amps. Anything less will be insufficient to turn the engine over. If none of these seem to be the problem then you have an electrical short somewhere between the battery and the alternator. ADDITIONALLY, i'd like to point out that many auto part stores will test your battery and/or alternator free of charge. So don't be afraid to stop there and ask for help.
It means there is a problem with the charging system. Can be a loose drive belt, problem with the alternator, or loose wire.
extra battery creating a start situation indicates loose connection or bad battery. I have also seen starters be damaged in the fields and armatuer that will activate with extra power.
I just had this happen on my F250. The manual says problem with the electical charging system. I went ahead and drove it until the power production completely failed. I am going to change my alternator but it could possible be the voltage regulator.
lost battery feed
