Basic Car Electrics Question
I have a question about the operation of basic car electrics.
The car in question is a 1999 Ford Taurus. The transmission wasn't shifting smoothly (right forum... SVX and tranny issues) and the car was hooked up to the diagnostic machine. The machine read that there was a problem with the torque convertor. In addition to that, the car was running at a constant 12 volts. Well, the torque convertor was repaired, but the car is still shifting real hard. According to the mechanic, it is still running at 12 volts. Now, is the car supposed to run at varied voltage or a constant voltage? Also, can these systems be related. I am thinking that this mechanic is less than reputable and trying to pull a scam. Any feedback would be appreciated.

The car's battery is 12v, but the alternator puts out current as well. My stereo capacitor has a voltimeter on it, and I've seen readings as high as 14.5v while driving.
However I don't think the voltage would have much of an effect on your shifting issue.

I am not going to disagree, but a lot of money could be wasted here, and I'd appreciate any technical feedback, if someone has some.

here's a good reference to decribe how it all works: http://autorepair.about.com/cs/elect.../aa122700a.htm i've added a voltage gauge to my last two Subarus because i like to know what's going on with the battery/alternator. its weird that they don't have them.
