Try this procedure:
Check the battery like this:
Turn on the headlights, then try to start the car.
If the headlights do not dim or go out, then the battery is likely ok.
Check that the battery cable plus post, goes to the starter, Minus post to a good ground, like the engine.
If wiring is ok, then look at the starter solenoid for a good connection, and proper voltage at the starter.
Problem is most likely the Solenoid's bendix gear or starting relay, Have someone bang on the starter while you try to start the car. This usually works by dislodging the bendix gear..
Hope this helps.

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.

2003 focus loses memory when tured off 2 mechanics said it might be a fuse what fuse is it car wont hold its memory


Check first the parts that is more accessible such as the terminals for the battery and any ground wires that may have come loose. If it is the fuse, inspect the fuse box for loose connection. If the fuse blows out after replacing, have the wires inspected. You may have wires that may be grounded due to bad insulation or bad connection. These may cause the ECU of the car to loose power and in turn loose memory.

Battery light stays on


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.

Ford Focus occasional starting problems.


Hey there...

Although I'm questioning why it would be doing this mostly on cold mornings, I would suggest that you check your battery connections. 99 times out of 100, the reason that this happens is because one of the battery cables does not have a good connection (Many times it's the ground wire). If you check to make sure that the connections on both ends of both cables are tight, then try taking your vehicle to your local parts store to have them do a load test on your battery. It's possible that the c.c.a. (cold cranking amps) are no longer sufficient to start your car. After awhile, batteries tend to lose their charge due to age, how many times it has been discharged completely, and also frequent cold weather. I believe that this should solve things, but feel free to contact me to ask about any other possibilities that may be causing this, as I'll look into any other similar common issues on your particular make and model. Should be battery cables or battery itself, though. Hope this helps and have a great day!
