The battery light has nothing to do with the battery itself, it is indicating that there is a problem with the alternator that charges the battery, most likely a defective rectifier bridge diode has failed.

The charging system on your vehicle is computer controlled . Your vehicle is a rolling computer .The instrument cluster has a microprocessor inside , there is also a body computer ( SJB ) smart junction box , Engine computer etc... they all communicate on a serial data network , C.A.N - controller area network . It's hard to know what's wrong when you don't know how it works . There could be codes stored in the computers , these will not always turn on the check engine light .

Battery light stays on


Check the voltage at the battery with the engine running. You should see more than 14 volts. If it is less than 13 volts than the alternator is no longer charging. Make sure you check for power on the large wire on the back of the alternator!

I have a ford focus 56 model and sometimes it does not start no mileage working and when it does start sometimes dash lights stay on and the accelerator is slow like a flat spot.


I have a 2006 Focus and I am having the same problems. I have already replaced the battery and it hasn't helped. This is not a constant problem. Only every couple of days and then she runs fine. However I have noticed my gas peddle sticking when I first try to give it gas. Then it clears up and runs fine. Any help would be greatly appreciated.

May battery light always on


This may indicate a problem with the battery or in the charging system. Take the car to an autoparts store and have them check the battery and alternator output. Most parts stores offer this service at no charge. Hope this helped and best wishes.
