First check your alternator fuse usually located in the fuse box under the hood. Also check continuity with a Volt Ohm Meter from the large red wire from the alternator to the fuse box. The plug that goes into the alternator should have 12 volts to one of the pins. Also is the check engine light on? If it is check for a DTC P0610 I believe. It is possible the PCM is bad. The PCM controls the alternator on that vehicle. Good luck and hope this helps.

Checking for B+ volatge at the heavy gage wire on the back of the alternator an the smaller gage red wire in the connector pin #3 . Without B+ voltage at those wire's it won't work . The other two wire's in the connector come from the PCM - engine computer . Computer controlled charging system .

Try reprogramming it.

1. Turn the ignition from OFF to RUN 4 times within 6 seconds.
2. Turn the ignition OFF. The system will chime to confirm programming mode.
3. Within 20 seconds, press any button on first keyless remote.
The system will chime once to confirm programming.

4. Within 20 seconds, press any button on second keyless remote.
System will chime once to confirm programming.

5. Turn ignition to RUN to exit programming mode.

SOURCE: Can't find where to loosen tension on Ford 2006 ZX5 Focus

There is no belt tensioner for this model. these run with strech belts. The new belt has to be fitted with a special tool, which some motor factors supply with the new belt kit. To remove the old belt you simply cut it. But fitting the new belt is a bit fiddley if you have never done the job before.

My 2006 ford focus zx4 had a low battery indicator light come on in town. On the highway with the ac on full blast and the radio on and cruise control on she started to lose engine power and the radio shut...


With a multimeter check the voltage at battery terminals. Should be more than 12.6Volts when engine off, and at least 14 volts with engine on. If the battery voltage is less than 12.6 volts then you need a new battery. If the voltage is less than 14 Volts with running engine, then the alternator is not working properly. A stop at AutoZone might help. They scan codes, and check alternators for free.

My battery light has suddenly come on and the alternator has started to make a noise do i require a new one or is there something else i should be looking at.this is on a ford focus st year 2006.


My ST alternator took some time to completely fail. During the decline, I saw all kinds of random electrical issues. My advice-go ahead and replace the alternator unless you don't mind needing to tow the car (or you travel really short distances). At some point, you'll find every electrical system completely shut down (one of your computers will funnel all available battery energy to the engine and fuel pump). From that point you've got a very short distance till the battery is exhausted. This doesn't mean the battery is toast!

Having the system tested is of little value. My car-the "BATT" light was ON when it was tested, and I was told it needed a new battery. Indeed, until the very end, the voltage provided by my alt was about 14.4VDC-even with the light on.

Replace the alternator now or do it later after a tow.

Sounds like your alternator is bad or the belt is loose/broken

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.
