Sounds like you have something that is on all the time and drawing power from the battery. Check, dome, courtesy, trunk, hood, glove box, and brake lights.

Why does 1994 Ford Taurus loses connection when trying to start and the battery and starter has been replaced?

This can be due to loose or corroded cables and or connections , and did the car start even at least once after the battery and starter was replaced? If it did you probably need a new alternator or if your handy enough you have the choice of rebuilding the alternator. Many stores offer free alternator testing , I my self have a 96 Taurus and i have had many problems over the years and now I'm at the point where my alternator is bad and i will soon be rebuilding it. If it is none of these issues then there is some thing more serious wrong in which case it needs to go to a mechanic who can determine and fix the issue.

There isn't a fuse for the alternator. The alternator is belt driven, and there'll be two lines coming from the alternator - one goes from the alternator positive to battery positive, and the other goes to ground.


My head lights get brighter during acceleration. I have replaced the alternator. What causes the battery light and the air bag light to flash on and off when driving a 1994 Ford Taurus Wagon 3.8L?

your alternator was never the problem. Its your battery and/or charging system. the reason the lights get brighter is because the car isn't getting the propper amount of energy from the battery and is having to directly draw off of the alternator. when the engine is rev'ed the alternator spins faster creating more current to charge the battery, witch is why the lights brighten at higher rpms.

Why isn't the rebuilt alternator charging that I put in my 1996 Ford Taurus GL?

Does your Bat warning light stay on or if you have a Voltage gauge what does it read. Was your battery fully charged before you installed your new alternator? Remove alternator and have it tested to besure that it was indeed the problem.


How many volts is an alternator supposed to put out on a 99 Taurus?

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.
