While the car in question is not a professional car, I am awed by the knowledge on this board so I thought I would give my problem a try. I own a 2006 Lincoln Town Car with approximate 167000 miles. Less than a year ago, the battery light came on. I immediately took it to my mechanic who diagnosed a bad alternator. With said alternator replaced, I felt I was free and clear. Not so fast. Within a couple of months, the battery light would illuminate but only for a minute or so and with no known pattern. Once, when on, I happened to be within yards of my mechanic, so I stopped by to have him check it out. While waiting on him to get his test equipment out, the light went out. However, in the process, my car overheated due to the fan motor failing. I suspected maybe that a failing fan motor was pulling too much thus causing the battery light to come on. With a new fan motor, I was on my way. Then, within weeks, the battery light came on again. Same pattern insomuch at that it would only stay illuminated for about 60-90 seconds. Shortly after that, I was greeted with a dead battery. With the car back at the mechanic, he assured me the alternator was functioning like it should and within the set limits and sold me a new battery. He also took the time to re-set the computer. Within a few weeks, we were back to the brief battery light. He said that he would do some checking around and thought perhaps a wiring harness had gone bad. In the mean time, the air ride compressor died. So, when I took the car in to have it replaced, my mechanic replaced the wiring harness. Hoping beyond hope that perhaps the air compressor was pulling too much thus causing the battery light to illuminate, I felt that the end of the mysterious battery light was near. But, it was not meant to be. The battery light has illuminated twice within five days of coming out of the garage. The only thing I have not done is take the car to a Lincoln dealership to have them run a diagnostic scan. Having done some internet research, I have read on a couple of message boards that some Town Car, Grand Marquis and Crown Victorias will do exactly what my car is doing and there is no harm and also no solution. So, any suggestions at this point would be greatly appreciated!
