You will need to check the alternator to confirm it is working, should be putting out 13.5 + volts. Another thing to check, with engine off, remove the positive battery cable from the battery and touch it to the battery post. If you get a lot of spark you have a short in the system somewhere that is drawing your battery down. It is normal to have a little spark because of you stereo memory, clock etc. If you find you have a major draw in the system the first component I would check would be the starter. Disconnect the wires from the starter and see if you still have the draw.

change your battery cables and check all wires on the alternator for loose connections, expecially the grounds.

SOURCE: 1991 ford festiva replaced alternator new

it is part of the alternator actually on a lucas unit, a small black box bolted to the rear of the alternator.

You may have a faulty ignition switch or a corroded engine earth cable causing the alternator not to reach charging voltage.

SOURCE: new battery and alternator and the battery wont

If it is going down after it is parked ,then it has a draw on the electrical system,or if it is going down as it is driven,then the large output wire on the back of the alternator is not getting to the battery,if needed,run a wire ,along with the original wire from the back of the alternator,to the battery to get it to charge.Other wise ,the system has a draw,pulling voltage from the battery with the car not running.

Battery drain overnight on pontiac 1994sunbird


The alarm light will not kill the battery. Your diode in the alternator may be bad. This will slowly drain the battery. Replace the alternator. Or charge it up and go to auto parts store and have them test the battery and alternator and starter.

1992 holden barina charging problem already replaced alternator but still slowly drains battery


It is not charging the battery because of several problems ---1 when connecting up the wires to the alternator was there a spark at the connection ---2 is the heavy wire on the alternator insulated from the body of the alternator--- is there a fuse in the charge circuit that is blown---4 is the light wires pushed fully home in the connection--- have you the correct alternator for the car ( internal or external voltage regulator)---5 is the drive belt in good condition and tight- If everything checks out then take it to an accredited auto electrician to have the alternator tested properly as new alternators ( out of the box new) can be faulty.

2000 pathfinder battery draining


Sounds like your alternator is doing nothing-the car is running only off the battery. Have your charging system checked-does your battery light stay lit? If that bulb is burnt out, that may be why the charging system is not working. On some charging systems, that bulb is crucial for the alternator to work.
Engine off, a fully charged battery should measure 12.5 volts with a voltmeter. Engine idling, and the voltmeter at the same battery should be showing about 13.5 volts. This tells you the charging system is working.

Headlights causing battery drain while driving?


Hi:
Though your car seems fine without using the headlights, you have a charging problem, and need to get a couple things checked out. First make sure your battery connections are clean and tight. Your alternator belt should also be checked to make sure it is serviceable and properly tightened too. Your alternator should be checked under load, and lastly, your battery too. Most auto parts stores, such as auto zone,will check your parts for free,so you should only be spending money on what is broken!

Wont start


Could be the diode pack on the alternator (or a short somewhere else). Disconnect the alternator to find out.

Charging problem.. Wont charge battery


The instructions for installing a new alternator usually read to fully charge the battery (12.3 - 12.8 volt range). Otherwise, the alternator will be damaged when it initializes. I have seen some extreme damage result from installing a new alternator with a low-charge battery. The torque required to turn an alternator when damaged in this scenario is unbelieveable!
