2000 Ford Taurus battery drain while driving. New alternator and battery stays charged in other vehicle. What is draining my battery.

Seen this "mystery drain" many times. Check spark at the battery to see how big the drain is. For this simple test, blow away any (explosive) battery charging fumes. Leave one terminal on and gently touch the other to its post in fairly dark surroundings. Then try it again with the wires taken off the alternator. Your spark is now probably much less. Usually bad diodes leaking electricity backwards through the alternator cause this drain. Replace the alternator or the diode pack inside it. Some mechanics recommend actually measuring the drain.... hahaha. OK whatever.

Hi, no the cam sensor will not drain the battery. Recommend you repair the cam sensor and then get a jump start. Hopefully this will resolve your issues. If not, please get back to me for troubleshooting steps.

Got a 1990 ford taurus and new battery and new alternator but still has 3 amps of draw .what controls the alternator? the wire to it ...

Unfortunately if it was a rebuilt alternator it may have one bad diode causing it to bleed amps and drain the battery. With rebuilds this happens a lot these days. Either have the diodes tested or demand a different alternator under warranty.

The battery in my 2000 ford taurus wagon drains over night and needs to be boosted in the morning what would be the problem? I put another alternater in it and a new battery and it still drains?

You have what is commonly called an "Ignition-Off Draw". Simply put, something is still on when you turn off your ignition and close all your doors. Aftermarket radios and accessories like remote start units and alarm systems can cause this. If you do not have any aftermarket equipment in your car, a very common problem is a glove box light or the lights in the vanity mirrors in the sun visors. If you cannot find anything obvious, then someone will have to connect an ammeter to your vehicle and start pulling fuses out to identify which main circuit the problem is located on. Once the main circuit is identified, then the sub-circuit can be determined by using the wiring diagrams as an aid. Once the sub-circuit is identified, then that circuit must be traced to find the actual source of the load that is killing your battery.

using a test light with all doors closed everything in the car off; disconnect your black battery cable then: connect a test light between the battery post you just removed the cable from and the cable you removed; the light should light. this is your short (leak) then remove fuses until you find the fuse that causes the light to go off your problem is in that circuit.
