2003 Focus SVT with Alternator Failure

The alternator failed 2 weeks ago and we had it replaced. Well, the same things happened again yesterday where all of the lights, PS, etc. shut down and the car died. The car was towed to the Ford dealer where the work was done and the alternator has tested bad. What could cause this to happen again so soon besides installation of a bad alternator?

Re: 2003 Focus SVT with Alternator Failure

hey i can kinda help solve your mystery alternator failure, the SVT focus has bad cables leading from the battery so go to autozone or whatever parts store you like more and buy new terminals. that should solve the problem. look at the way they are clamped to the battery, ford screwed up on that part

The terminals at the battery flat suck. They can be super tight with a wrench and still be loose enough to pull off by hand and especially if the battery posts have been cleaned to remove some slight amount of material.

Make sure the replacement alt is a Ford official Motorcraft one and even possibly an error there. Many dealerships here use the commonly available 'lifetime warranty' OTC part at the local parts stores, they then overcharge for the work while letting you think the parts are official Ford ones. The Chinese rebuilt alts now used are utter garbage and very common to fail as many as 2-3 or more and quick now, they use substandard parts since they know the warranty will have them replacing the alt every time they turn around. I know because I had to pretest every alt sold, and MANY failed right out of the box. One of the most serious part issues out there now.

The harness to alt can be bad as well, there is a replacement pigtail to fix that.
