Try another battery if this doesnt fix it you may need a new alternator alot of new cars and trucks will not run with out the battery hooked up all the older cars you could jump it and it would run off the alternator but times have changed cars are different before I would waste money on a new battery I would borrow one from another vehicle just to test it if the problem still exist than I would say you have a weak alternator also make sure all your connections are clean and tight at the battery and starter

SOURCE: 2000 ford expadition battery/alternater problem

I have a 2000 Ford Expodition, After changing the alternator for the third and final time, I jump started it several time till I could get it to a repair shop, the owner looked at several things and did a few test. then replaced the #1 fuse a 20Amp Power point fuse that was blown. it has worked fine ever since. BTW he did not charge me anything, made a new firend and customer.

SOURCE: My 1984 ford f250 keeps loosing a charge. I

that is the quickest way to check the alternator leave it iddling and disconect the earth cable if it stays running its ok or my own way would be to use a volt meter and if it has about 13 volts or there abouts its ok and that would suggest a faulty battery or somethung draining the current wken its not running

Check all electrical connections from and to the altinator, if everything is good then its possable your remanufacterd altinator is deffective, the parts store can test them for you. You can never trust remaned parts theres always a chance that its a bad part.

1995 yukon has a new battery but usually needs a jump to start


First off the gas thing might just be coincedence, second sounds like an alternator problem to me. Try this make sure you do not leave any lights or doors open for the battery to drain at night, Make sure your battery terminals are clean and tight, then to test to see of it is the alternator start the engine and with it running disconnect the battery terminals. I can not remember if it is the positive or the negative terminal to disconnect, so carefully start with the positive then the negative terminal and disconnect them from the battery. Be sure to not let the terminals touch any metal while one side is still connected to the battery. If the alternater is bad the car runs only on the charge of the battery, so once the terminals are disconnected from the battery the car will die. If it stays running then the alternator is good. Then I would look at the starter, TO be honest the only way I can truly diagnose the problem is to see for my self. To see if there are any noises, signs of other issues, Or clues that would help rule out the number of possibilietes.
Hope this helps

Installed new baterry and new alternator...battery or alternator dies in one day


the alternator will not die in one day unless there is a direct short causing diode or coil winding failure which would give signs of smell, melted wires. Disconnect battery and give full charge. what year is this? while vehicle is running you should be able to briefly disconnect positive battery post connection and vehicle will still run if alternator is good. For a new battery to die in one day, one of two things i think has happened. Either the batt is faulty from supplier,( not likely but i have seen it ) or there is a direct draw or grounding taking place whether its direct in the starter selonoid or a direct draw through accessories. Are you sure all switches are off ? Push switches (on interior lights) nothing like dome lights,delayed lights are staying on! Does vehicle start hard like it almost needs a jump. If it has to be (and it takes time). to find out what is drawing the power ( i am old school) disconnect positive power source on batt. 2) disconnect ignition power source on starter. 3) connect pos batt wire to starter, 4) touch positive cable to positive batt post and look for spark or contact. if this reacts then selonoid or starter motor is shorted drawing the current. Or if you have volt meter and know how to use it, this is good to. If checks good then hook ignition connection back on starter.(disconnect pos terminal on batt prior to re-connect) I think the battery is having the life sucked out of it by a short in the system ( A DRAW ) this could be a quick find or fix or this could take days to track down. alot of variables here to try to explain. but i would seek into the starter first as usually this drains the battery quickly .

A bell keeps ringing and a light flashes


It is your battery it is low or the battery terminals need cleaning disconnect the bettery cables and take a piece of sandpaper and sand the battery post until it is clean and do the same at the cable end and connect them back up if it still wont start jump it and then disconnect the positive battery cable if the engine dies when you disconnect the cable then you have a bad alternator

Every time i try to turn on car i have to boost it to get it going, and as soon as i turn off , have to do again . now i pulled off positive lead to battery while car running to see if it was alternator...


1st...never, ever disconnect the battery terminals when the vehicle is running.If you want to test the alternator's output, use a volt meter to measure the voltage at the battery when the engine is running. Your condition could be related to the battery itself, it may have cells inside that are shorting out, it could also be a bad terminal connection at the battery. What needs to be done is a voltage test to verify the battery condition and alternator output. I hope more problems were not caused by disconnecting the battery while the engine was running.

ALTERNATOR REPLACED WORKING OK NOW TIMING BELT PETROL AND BATTERY WARNING LIGHTS ON WHEN ENGINE RUNNING AND A/CON NOT WORKING


If your battery warning light is on, then your alternator is NOT working okay. Rather, maybe the alternator DOES work, but the battery light can also come on if your battery won't charge.

Put a voltmeter to the battery terminals when the engine is running and rev the engine to a medium idle. Battery charging, (engine running) it should be about 13.5-14.5 volts. Engine off fully charged battery voltage should be 12.6 volts.

Quick test-engine running, disconnect the positive battery terminal from the battery- if the engine dies, there is still an alternator problem.

Hope this helps.

Just had a cam shaft sensor put in my 2000 chevy tracker and my service engine soon light came back on vehicle runs fine


You should disconnect the battery cables, negative cable first then disconnect the positive cable from battery and wait ten minutes (this is a good time to clean the terminals and connectors at tis time). The check engine light should be reset and disappear if all is well.

Engine suddenly dies, all electrical goes out as well


Sounds to me like a poor battery cable connection. I am not familiar with the BMW cable routing but it should be simple enough to follow and repair.

First disconnect the negative cable from the battery and leave it disconnected until the final step.

Dicsonnect the positive battery terminal, clean the battery and cable terminal with a wire brush or light sand paper. Apply some dieletric grease or light coat of chasis grease and reconnect the cable to the battery. Follow the positive cable and do the same procedure to all connections down to the starter. Along this route you may notice a smaller wire connected enroute with a fusable link or fuse. Make sure to check these for loosness and or melted wire coating this can be a sign of a loose connection and your problem.

With the positive cable connections completed and reinstalled. Do the same to the negative cable, remembering not to reconnect the negative terminal to the battery until the very last step.

Sorry I don't have more knowledge of the wiring on the BMW.

Hope that helped.
Good Luck
