Ford Focus Battery Warning Light

Hi, my Focus started playing up a couple of weeks ago. All of a sudden it started loosing power (drive and electrics), the battery light came on, then the ABS light , then the whole console light up light a christmas tree and the car completely cut out and wouldnt turn over. A mobile mechanic came out and replaced the alternator and the power returned and the car now drives fine, however the battery light still comes on most of the time, so I replaced the battery. Problem remains. The only thing I can see as unusual is that the rear windscreen demister will not work when the battery light is on, but works when the battery light is off. I have changed the fuse relating the the demister but the problem remains. I have been told to ignore it if it is not effecting performance, but i am nervous as these things happen for a reason and I dont fancy loosing my electrics at 70mph on the motorway. Any ideas gratefully received? Cheers, Nick

By any means i am no expert here, but have you tried to have it scaned, maybe it will show something relating to the problem or maybe not. was the battery full chg. when he put new alt.on if not, not good, the reason i say that is if battery is low and you have a new alt. it can burn up diods in alt. because it has to put out so much power to charge battery back up it can burn its self out. what i said here is worst case senario it may have or not, have alt. chk. at the very least give you peace of mind. have it scaned, it might be something in computer that can only be reset by a scanner. hope i dident make you to nervous here i did not mean to. good luck.

2008 Ford Focus warning light question... sounds a crazy question... what I'm trying to find out is whether I may have been had and sold essentially a scrap car?

It is possible, but don't jump to conclusions yet. You need to get a code reader on it and find what the problem is. It is usually sensor problems. Some sensors are expensive though, some are awkward to replace. The sensors are attached to the ECM computer, the engine management module. If you only got the vehicle 3 weeks ago, you could phone the seller and ask if he has a code reader, a scrap dealer may well have one.

How should I go about diagnosing and repairing a 2002 Ford Taurus with 50,000 miles that is giving off multiple transmission error codes but shifts and runs fine and has no symptoms other than the war

Was the car parked because it had these codes 2 years ago? You need to check all connections for corrosion and or being loose to start with, including the battery cables and then load test battery.. The codes indicate that a sensor or solenoid is not getting power. There is no easy simple way to find out which it is. You will need a book to guide you through steps of diagnosing because the circuits have different voltage signals at different connections.

Ford focus 2005 battery light stays on new alternator , battery only 6 months old

First, a bad battery doesn't turn the light on. Just A bad alternator or ECM. Start the car. put a volt meter on the + and - sides of the battery. If it reads 12 to 15 volts (closer to 15 for a new alternator). The alternator is good. And is charging. The problem is the wiring or the ECM. It can be bypassed to turn the light off. I just did it a week ago. Problem is , I don't have the wiring diagram for your car. Don't get a book from the parts store, it won't tell you. Go to alldata or Mitchell and purchase a manual. It's online and lasts a year. But they give you good electrical schematics...

Ford focus wont start

Check the make sure the battery connectors are connected. Sometimes the cable comes loose from the battery. Check your battery see if a jump will start it. If it does it could be your battery.
