On a 1998, you can kill the running lights by pulling the the 15 daylight running light fuse in the engine comparement fuse box. Manual says to disconnect the battery before openning this comparment.
could be alternator or charging circuit or could be anything got to do with the battery when its draining out loose connection terminal
Check the dome light. These cars are notorous for having a bad door switch.
You will destroy the voltage regulator if you unplug the battery while it is running, then you will have to replace the alternator anyways.
I just had the same problem and replaced the daytime running lamp module. Ford part # xl2z-15a272-ab. This part is located behind the drivers side head light and gotten to thru the wheel well.
There is a DRL relay in the box under the Hood. You should note that if you are in Canada, the Daytime Running Lights are MANDATORY on all vehicles sold in Canada since 1990, and disabling them may cost you a LOT of money in fines, as it is against Federal law, and the Highway Traffic Acts of most Provinces.
How many quarts of transmission fluid does a 2004 Taurus 3.0 OHV require when draining transmission and replacing filter
BCI group size ( 59 ) Originally equipped with Motorcraft BXT-59 battery ( 2008 Ford Taurus )
According to the 1999 Ford Taurus Owner Guide : # 30 is a 15 amp fuse for the high beams , daytime running lamps , and instrument cluster
If you're absolutely certain that the battery is ok (have it tested) and that nothing is being left on and that the key is turning off properly, it's time to have the alternator tested. Sometimes an internal diode can fail which will end up draining the battery. But don't just replace the alternator. Take the vehicle to your local auto parts retailer and have them test it for you IN CIRCUIT! Meaning that they'll test it with the vehicle running. They should be able to determine if the alternator diode has shorted.
Defective alternator, dead cell in battery, or something is on pulling power from the battery.
burn out the fuses
i had the same problem on my Taurus 06. check the battery and it's connections, something is loose. i have changed the battery and cleaned the the terminals. every thing turned ok
I was looking at the 2002 Ford Taurus Owner Guide and it shows that Vulcan , Flex Fuel , and Duratec - V6 engines came with the ( Motorcraft BXT-36R ) battery
I'm not sure about all of these, but I have a 98 Taurus and the battery light came on. After a few days, the car died altogether and I had to replace my alternator. I would definitely take the battery indicator seriously and have your alternator checked.
With the engine running you should read from 13.5 to 15.3 volts at the battery with no lights or accessories on, with a nominal voltage at idle of 13.8 to 14.2, depending on temperature and battery state. Any less or more and the alternator is bad.
At the front of the engine compartment on the drivers side
In the Power Box next to battery.
Yes, it is in the PDB next to the battery.
Your battery is not giving full performance.
Something is wrong in the 94 Taurus reverse light circuit. There is probably a short causing the battery voltage to drop when the car is in reverse.
