Is alternator bad? I've had the battery for 4 years, never any problems, first the fan and alternator belt started to sqeal, after it was tightened, it was fine, then I drove it at night about two blocks with lights on, when I tried to start it, it just clicked and nothing worked, it started right up with a jump, when I turned it off and tried to restart it, it wouldn't start.I put in a new battery and it started right up, I don't know if the alternator isn't charging the battery or if it isn't driven enough, I only drive it about 100 miles a month on short runs, i've had the car 17 years. The battery never gave any sign of being low, the warning lights haven't worked since I bought the car. How can I tell. A friend put a gage on the alternator it just went on 12, I have a six cylinder. Help!

It should be 14 to 14.5 and yes the alternator could be bad

batterys only last 4 to 5 years anyway. Not abnormal for sudden failures.

That could be a bad starter motor. Check for voltage to the little wire on the starter solenoid

A few times before, when I turned the key on it would make a grinding noise like the starter was on, that happened about three or four times, then it was fine again. The first time tonight when it did start, I checked the lights and they didn't dim or get brighter. All electrical worked, its just clicking, non starting

I would like to explain how this started. The car ran fine, drove two blocks with lights, no dimming, went back out after 1hour and half, car wouldn't start, just clicking noise. Had jump start, it started right up, ran it a bit then turned it off, went back out after about an 1 hour and would not start, same clicking noise. Bought new battery, started right up, went two blocks back home, when it got dark, I tried the lights and they were fine with engine running, didn't dim, nor brighten. Next day, wouldn't start, just clicked. Thats where I am now, i've never had any trouble concerning this.I don't know anything but basics, but I can't make sense of the way this happened
