Hello and thanks for using Just Answer.

I will try my best to help you with your question.

You will first have to check a couple of fuses on your Taurus.

Fuse #26 in the engine fuse box and fuse #11 in the dash fuse box. Make sure both fuses have power on both sides of the fuse when the engine is running.

If the fuses are good, start the engine and see what the voltage is at the battery cable post on the back of the alternator. It should be over 13.5 volts.

 

Do these checks and let me know what you have.

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
