How old is the battery; after 6-7 years you're on borrowed time. Measure voltage at the battery terminals (with the engine running); should be about 14.5 volts. If it is only about 12.6 or lower, the battery is not recieving voltage from alternator (even if alternator "tests" OK). Check to see if battery clamps are loose or have a layer of corrosion between clamp and battery post. Even if they "look OK" try cleaning/re-tightening. Also check that the wire from the alternator to the battery is not broken, corroded, disconnected etc. Check the alternater ground connection. Other things that make the battery go dead: leaving the head lights on, or even the marker lights, a brake pedal that doesn't return all the way "up" and leaves brake lights on, dome light left on, an electric radiator fan that sticks on, any of a number of electronic gagets that were supposed to turn off automaticlly when ignition is off, but don't, an ignition lock that is so worn out that it allows the key to be removed when the ignition switch is not in the "off" position. If the battery keeps going dead try disconnecting the positive terminal (with engine off) putting an ammeter in series between battery post and positive wire; if any significant current is noted, try pulling fuses, one at a time, until current draw stops to determine problem area(s). Have patience; these electrical problems can be time consuming to solve.

first is battery totally dead or just won't start car, second only fords have silinoids for starters, if just wont roll over check for dirty terminals as above that is leading reason for no start, second appearently you have volt meter (tested Alternator) with volt meter on battery try to crank if volts drop below 10 battery is bad. now dead battery if the battery got completely drained somehow most of the time it kills them they will not hold charge more than few minutes ever again, go get a new one. I always recommend a light coat of spray on anti corrosive when replacing battery clean terminals thoroghly and spray on you can get it in a single use spray can at parts house. don't think you have to use it all just a light coat you don't want it all over battery top it is a neuralizing agent if it gets in battery somehow (vents or non sealed battery) it will neutralize that too) have seen people kill brand new batterys this way.

When the battery is dead, nothing works...no lights on the dash or anything. If you have lights, the battery may be ok and the starter may be bad>

yes check the starter, its connected to the battery. and it will drain the battery, if the starter doesnt turn the motor over.

I have started more dead cars by just cleaning the terminals and clamps with sandpaper until they shine and tightening them securely. Start with that. If that's not it, take out the solenoid and go to a good auto parts shop. They should be able to tell you if it's bad before selling you a new one.

If it turns and chugs, it could be a weak battery.
If it just clicks, it could be the starter.
