This sounds like a bad activating circuit. The ignition switch is suppose to send juice to the Alternator. Also the plastic plug connectors holding the small wires into the Alternator can ride up and miss the metal tabs they are suppose to fit on. Mechanics often pull the metal connectors out of the plastic connector, then slide the metal connectors onto the Regulator tabs inside the Alternator opening. The Mechanics slide the plastic connector housing over the already attached metal connectors and call it a day.

SOURCE: battery wont charge

i had this exact same problem ... under the hood onthe left side of the firewall where your starter solenoid and fuseable links are there is a little container type thing that holds a 20 amp fuse that fuse is probably blown the little container is on the firewall right below the fuseable links

You have installed many parts, but missed the
entire process of repairing any vehicle

First you have to learn the system your about to work on,
by looking at wiring diagrams & also gather other info from
various sources,so you can have a point to start your testing

If all I do, is go by what you wrote here

I would say you never did any testing ,to even
find a problem

No mention of checking for codes

That is what you do, after you confirm the battery
is good,fully charged & holds a charge & test it

Battery light come on when driving and then goes off

When the battery light comes on it is telling you that there is a problem in the charging system. Have the charging system checked by a mechanic. Most likely the alternator is starting to fail.

Ford focus wiring

same thing happened to us.  My wife came home and said the rear brake lights were stuck on so I assumed it was the brake switch...not so. Took car for a ride and noticed rear wiper did not work and when I hit the brake the rear hatched opened and door locks blew out.  I started by looking at the wires in the gromet above the hatch and found almost all the wires were bare.  Therefore power was jumping  the bare wires and traveling back down the third break light and to the rear brake lights and visa versa.. a very dangerous situation.  The best that I can tell is the wires are so short in length that they pull and chafe every time you open and close the hatch...very poor design...   Note: we bought our vehicle brand new and some of the wires had electrical tape on them....seems mickey moused.

2003 Ford Focus battery light is on, but alternator appears good

Disconnect battery ground for 30 seconds & reconnect. Light should be out unless you have deeper diagnostic problem. Charging system good Battery good. This action should reset trouble light. Good luck!

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.
