    You need to run a parasitic draw test on the electrical system which will isolate the drain. Have a trained technician look at it to save you time and grief

SOURCE: battery drains down over night,new battery alternator is charging

ck to see if you have a trunk light or under the hood light if so remove the lamps from the under-hood light and the doom light and the trunk light then put the fuse back if this fix works then one of the switch is staying open and letting the light continue to burn , if this does not fix try to get someone to unplug the wire to radio then replace fuse see if this is a fix it is a process of elimination and some times takes several tries, good luck and if you have more question feel free to ask without a volt meter and electrical knowledge this is a simple test you can do and it cost nothing but time

SOURCE: battery drainage


Possibly any of the diodes inside the alternator (most likely). In some instances, it could also be the regulator whether it be internal;/integrated to the alternator or external.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

My battery goes dead when parked overnight

You have something draining the battery. You will need to try to isolate what is drawing the electric while it is parked. Try pulling out a few fuses every night until it stops going dead. Then you can narrow it down which circuit has the fault. Try the radio, alarm system or interior light fuses first. Write down which fuses you pull out so they can go back where they belong. Good luck!

Something is draining the battery

There are a few things that I am sure you are aware of that do produce a draw as in stereo memory etc. How fast does a fully charged battery draw down? Are you aware of procedure of how to test for draw by pulling fuses?

My van battery is good what could cause it to drain the alternator is good

something that is always on such as alarm systems, remotes, clocks, computer, is now drawing too much current which kills the battery. brother in law installed aftermarket items loom large on the list, the way this is determined the **** way is to pull one fuse at a time and let it sit over night. when the fuse is finally pulled which, when left out, allows the car to start the next morning you have begun to isolate the bad doodad as it is on the circuit of that fuse. another faster way to do this is put an ammeter in line with your battery and begin pulling fuses until you pull the fuse which cause the amperage to drop down to almost nothing. you have then isolated the circuit on which the bad doodad resides. you can live without that doodad or replace it.

Hi, A 2002 Hyundai Elantra Hatch is continually experiencing a flat battery overnight, & the only way to prevent this happening is to disconnect the battery every night. What could be the cause of...

You evedently have something pulling on your battery. I can explain to you how to at least narrow it down as to which are in the electrical system is doing it. Get your printer ready to print and I'm going to do my best since i am assuming you don't have any special tools. You will need a test light (12 volt) to begin with. Now disconnect the negative battery cable connected to your battery. Connect the clip at the end of the wire on the test light to the battery cable that you just disconnected. Then take the pointy part of the test light and touch it to the negative terminal on the battery. If it lights up real bright that means you have something in your vehicle still "on" and that is what is pulling the power from your battery. Now there will always be at least a dim light when it is first touched to the battery due to stuff like the interior lights if they have a timer as well as stuff like your clock. Now if it does have a bright light begin to take out one fuse at a time. When the light goes out when you take one of the fuses out you have found the circuit that is pulling the power from your battery. From that point on you will need to find out what that fuse controls and check the componants on that circuit to see which one is pulling the power. That's the best way to at least narrow down the circuit then the hunting begins to find out what it is. Worse case, If you can't figure it out or until you do, you can at least just pull that fuse out until the next time you drive it to prvent it from making your battery go dead. Most likely that is easier than disconnecting the battery everytime. Now if you don't have a bright light, I would have the battery checked. I hope this helps and good luck.

Battery keeps running down, what is the best way

The new alternator may have a closed regulator draining the battery,put a volt meter,or test light in line with the ground cable,remove the ground cable,and put the test light clip on the ground cable,and the tip of the test light to the negative battery post,or contact,it does not have a post,If it lights the test light,and it does not fade off,then there is a draw,unplug the alternator regulator plug,see if that turns the test light off,if it does,then the alternator is defective,then if need to continue testing,remove the interior light fuse,completly,and then pull one fuse at a time,to see if the test light goes off,when it does,that is the circuit that is drawing the battery down.The clocks will pull to many amps sometimes and cause this also,be sure to disconnect the battery over night to make sure the battery is good also,so you wont be doing all this for nothing,and you may want to have the battery load tested.

Battery runs down if car left overnight

Have you done the tried & true method of connecting a test light in between your + battery connection & battery post? Simply remove battery+ connection, attach test light from it, to post at battery. As long as test light is lit, you have a draw. Brighter the light, bigger the draw. Of course you'll have radio memory etc, so I just pull those out from the start. If you know where they all go back to, I pull them all out, and when light is out, I start reinstalling them one by one, when light comes on, I note it, remove it, then replace next one, until I've recorded all the draws & noted which one(s) that made the light come on the brightest, then do my research around that or those particular circuits. Quite often you can watch light & pull one at a time & will suddenly see light dim quite a bit, and that is a good indicator of big draw circuit.
