Check to see if the alternator is charging the battery properly. Use a voltmeter - if fully charged battery should read approx. 12.8 without engine running Should read approx. 13.8-14.2 with engine running if alternator is working properly
you can make a light bulb by holding alt + 20.
Battery Light OnCheck for bad alternator. alt. is goodbattery is goodchecked fues goodwhat about wiring
Does alt. light stay on after car is shut off? If so could be voltage regulator is defective and overcharging battery when running Does light stay on after car is shut off? If so could be a bad voltage regulator--if so may be overcharging battery Check voltage readings at battery should be around 14.2 with car running -- if much higher than this voltage regulator is bad.
If the light remains on then the system still isn't charging as it should. Check the plug on the alternator and also that the wires to the alt have a good connection.
The alternator has A specific connection that is for this job, When there is power to the alternator and the alt. is not making power it will light the bulb. When the alt. begines to make the desired amount of power it will automatically turn off the bulb. If the light is removed the alt. will not charge, because the light is also used by the alt. as verrification.
it's either your wiring or the wrong alternator or a bad battery !!
you may need to change or adujst the alt belt.
It could mean the alt is nearing the end or a loose connection of the alt wiring. TAkeit to auto zone and have the alt. checked
Check at the battery with a volt meter, Should have over 14 volts when engine is running. If not, possibly have to replace the alt. or check all the wires.
There are several things that can cause your 2003 Ford Windstar alternator to start charging. Make sure all of the connections are clean and secure. The voltage regulator might be malfunctioning.
