Well, you start with the battery. It needs to be FULLY charged, that means about 4 to 6 hours on a real charger. Then you load test the battery.
If battery checks out okay, pull the alternator and have it bench tested, specifically test the diodes for open.

To narrow down the offending system/item: pull interior light fuse, and clock fuse, disconnect negative battery terminal, and put a light between the cable and the battery terminal (or a volt meter). if the light lights or you show voltage, disconnect circuits, one at a time, and retest....Eventually you will find the offending item.

Brand new battery and alternator but keeps turning off. I have to keep jumping the battery. What's wrong?


Check the alternator output with a multimeter. You should get14volts out of the alternator (I purchase brand new alternator and sometimes there no good), it happens, check the big wire coming out of the alternator, if you dont get at lease 14volts it's no good (it's got to generate more than 12volts).good luck.

Car would not start. Was able to jump it. Battery is less than 1 year old. Could it be the alternator?


It is possible you have an alternator problem. In most cases, if the battery is dead and you jump it and the vehicle will stay running, the alternator is usually ok.If the battery is going dead sitting overnight, you most likely have a parasitic draw on the electrical system drawing power from the battery when the key is off.

What's your problem? EVERYTIME I SHUT MY TRUCK OFF, I HAVE TO GET IT JUMPED, COULD IT BE BATTERY ALTERNATOR OR SOMETHING ELSE? PLEASE HELP, I'M BROKE AND HAVE TO TAKE MY SON TO A FREE CLINIC...


right get a jump start then with engine running take a battery lead off ,say the negative one and if engine keeps running then you need a new battrery ,if it stops you need a new alternator ,now if it keeps running and battery going flat overnight try leaving the lead disconnected on the battery overnight in case a diode is playing up in the regulator on the alternator ,or a boot light or something similar is staying on.

Dirty connections or corroded cables. Clean and/or replace what you can on the + and - side. + to the battery and the +starter position, and especially the - from the engine to the ground The ground is VERY important to look at here, since it is a jump start that makes it go. Let us know.

The car won't start let alone keep running. The battery light was on for awhile but the car was running fine. Then I was driving and it just started sputtering and died and even when I jump it it only...


Get the battery & the alternator checked (Autozone, O'reilly's or even Pep Boys can do that for free). If the alternator is out or going out, it's not charging your battery - that means everything electrical in your car is now trying to run directly off the battery & draining it (it doesn't take long - especially if the lights or A/C is on). If those check out ok, take it into a mechanic & have them run a diagnostic - you may have a relay out. Good Luck.

What could be wrong if the battery light came on and not long after we lost power? when we got a jump start two times it would not hold the charge long enough to even move it?


It sounds like you have a bad alternator. Be sure to check to make sure your battery connections are tight and clean. If it is your alternator you will need to charge your battery before you run your car after replacing your alternator. You may also have a bad battery but generally if you jump a bad battery your car will stay running as the alternator will keep it running but if you ran your battery dead a simple jump start will not keep the car running if your alternator is bad. Most part stores can test your alternator and battery. Your battery will need to be charged before it can be tested. They do not need to be in the car to test them.

Needs jump


Check the battery for charge and alternator for power (free at Autozone) It might be deposited/rusted contacts on alternator and battery to reduce the electric current to battery from altrnator so battery just draining out. Also if it is very cold overnight (less than 0 F) battery lost the cranking power.
Please kindly let me know if the information provided was usefull for you or you need more info
Good Luck
