We have replaced the battery, alternator and starter. we just replaced the alternator 2 days ago and it worked fine the first two days but now its doing the same thing (wont start just makes a clicking sound). what would cause the baterry to keep going dead like that even though it has a new alternator and battery?

Ronald,
When you replaced the starter, I assume you did disconnect the battery. Did you clean the posts before putting your battery cable back on? I replaced my battery a couple of months ago and did not clean them and my van ran fine for several days and then one day would not start. Cleaned the posts and cable ends and everything worked fine. Just a thought. Hope this helps!
the starter only turns the motor when the key is turned. the alternator charges the car when its running. if its dead you left something on to kill the battery. charge the battery. then get the charging system tested. advance autozone and I am sure other parts store can check the car for free
3 days on a new battery, yes it is significant. Four things can do this in a short time. alternator, starter, radio, and interior lights/ light switch. Alternator can be checked on the car, A sign for the starter is that it may drag or drag sometimes. Radio is lights staying on after the door is opened,Even the clock. Light switch is interior lights don't work or the dimmer switch doesn't work. These are just suggestions that I have run across. They still need to be checked. It can get costly.
Sounds more like a faulty battery terminal to me from your description ,try cleaning and make sure its tight then smear with petroleum grease.Clean terminal with a kettle of hot water first
First you can not test an alternator by disconnecting the battery cable. That is what we did back when cars had generators. Today you can fry the computer and alternator running the engine with the battery cable off. Meanwhile, I would look for a fuseable link or main fuse problem. The alternator circuit may not be connected to the fuse box and battery.
bad alternator possible or bad battery..even though its new that battery can be bad. I would take a volt meter and with the engine running check the volts of the battery..If the volts are 12 you need to replace alternator, if volts are 14 you need to check the battery. to check the battery hold the volt meter to the battery and have someone start the car..while the starter is cranking battery volts should not drop below 10volts.if they do your battery is bad.
