You have not unplugged everything - otherwise you would have found cause of drain. Hook up ammeter to battery and turn ignition off. Wait about a half hour - take reading on meter then and one by one disconnect and reconnect individual fuses until you find the circuit that has the item drawing the juice that is draining your battery.

Hooked up my new battery backwards, blew the main fuse. It has been replaced and now the meter fuse in the inside fuse box blows within seconds and gage cluster and alternator not working

Could have damaged regulator. When the car is running have you checked the voltage at battery terminals. If battery is charging it should be around 14 volts. If around 12 your charging system is fubar.

Meanwhile if you have to charge the car every day then something in the car is draining the battery, Using an ammeter you need to track it down, Hook it up to battery and pull fuse out one at a time till the drain goes down. That isolates the circuit with the problem.

Battery wont stay charged

If the alternator is good and the battery is new, then something is draining the battery while it's parked. In the old days people left their headlights, radio or something on and this drained the battery. Now a days this is not as big a problem with 5 minute timers that turn off lights if you forget. I would take it back to whomever did the alternator work for an answer. How old is the battery? You can take it to see if it can't hold a charge any longer. In my experience, most batteries don't seem to hold a charge after about two years. Did anyone do some custom work in your car that requires electricity? It could be this extra stuff is draining the battery.

My battery was bad, so I had it replaced and the car worked fine for a few days. One day while out running errands I went to start the car and nothing happened. No sounds, etc. All of the lights work...

Sounds like you have a dead battery again. Who install you battery? Did they check out the charging circuit on your auto. If a professional mechanic installed your battery then have him check everything out; such as, cleaned battery terminals, the ground strap is solidly connected the body, charging system is working. If a professional mechanic didn't install you battery.

Remove the battery from the car/truck and have it fully charged. Clean the ground and positive terminals with wire brush until the lead is bright and all the corrosion is gone. Clean the battery terminals until the batter terminals are bright. Get a couple anti-corrosive felt disk---they look like two big felt washers, one red (+) and other is black (-). Insatll the battery and make sure the terminals are tight. Start the car/truck and while the vehicle is running take a voltage test across the battery with multimeter, volt meter, etc. The voltage across the battery while the vehicle is running should be 13.8V to 14.1 volts. If not, Have the alternator check out!

Like you said you have had everything check out. Check it out again. If everything check out again then there is a internal component, wiring shorted which pulling current the battery and could drain the batter of current within a few days.

If you are using your car for a few days to running errands. You car will run on the battery with no charging cycle working. Once the battery voltage falls below a certain voltage point the computer will only limit certain electrical components work, door locks, maybe one window and this is iffy! The reason why you can't get the transmission out of park is the locking solenoid that operates with the brake switch will not function. This function is a safety procedure that is Incorporated within the vehicle design. . GB...stewbison

New? then, go to the dealer where you bought it. It must be still under warranty. It's not supposed to be
leaking since it is new. Otherwise, you have no option
but to buy another.

Battery Drain when parked.

First off, how old is the battery? It is possible it might be stratified and its just no longer holding a charge well. I've had batteries that are 2 or 3 years old and then they just go dead if I don't start them up every day or so. (Some batteries are just made better than others) If the battery is brand new, then check for some possible wiring shorts. Try looking at the engine running in the dark and try moving around the wiring harness to see if by chance you see any sparks or arcs of electricity. Other than that, you might have to have a qualified auto electric mechanic to check it out for any abnormal power drains.
