SOURCE: truck won't start

You should check your battery cables with an ohmmeter and see if they have any resistance,they should be at 0 ohms or just alittle over,but could possibly be the starter solenoid also.I had this same problem with my Toyota last year,hard starting sometimes needed a jump and then the alt went bad,turned out to be the solenoid was shorting intermittantly.Hope this helps.

SOURCE: Battery is dead, had it charged, meter read 14

was the battery tested? that is the 1st thing u do after charging, very likely the battery has a dead or shorted cell, this drains the battery down very quickly, Kragen and Autozone will test the battery and the charging system for free, suggest you have that done.

SOURCE: With the Battery charged it will go dead sitting

theres a draw somewhere. these are sometimes hard to pinpoint.start by checking that all lights turn off,glovebox underhood light all lights,you will need a meter to meter the draw amps, then with key off doors closed look at the draw amount,.02 to.03 is allowable, start removing fuses and watch if amps drop,one fuse at atime, start with this to try and pin down a location of the draw.hope this helps.

SOURCE: 1991 ford ranger thought battery

before u decide the battery has an outside draw on it have the battery load tested, Kragen, Autozone and many other parts stores do this for free, when a battery is run dead like this it can develop a shorted out cell and this causes an internal draw, after u have verified the battery is good the next thing to do is go out at night and look for any lights that may be on in the interior, if u have lighted visor vanity mirrors make sure those are not on as well, also check consoles and glove box lights and cargo light for the bed.

I have a 1992 Cadillac devile 4.9 charging issues Help????

Deville 92 old. lots to find bad that old. !
here it is, ID #2 below
you were told wrong, the reg is inside the ALT, actual.
the internet lied again.; 1/2 the time, asking 8year kid same.

the top parts sellers online,shows, no REG outside, so strike 2 on reg outside.

learn to keep that old (how old is it?) battery charged fully until car runs perfectly. or it can take 1/2 to jump start it or worse. dead batteries do not start engines and overload the poor donor cars electrics, doing so.(jumped)

once battery is new, or charged or load tested in a real shop
start the engine, see if GEN/CHARGE lamp goes out.? on dash.
if not alt is bad. wow no fuse then, scary then. lots of car fires.
or use voltmeter idling, at bat terms. 13,to 15vdc good below ALt is dead
140amp alt here.

I got the battery changed it worked for 2 hrs then it went blank i replaced that battery but still dead what did he do wrong

What make and model?
If your battery goes flat after being charged, and a new battery does the same, then there is something that is draining power from the battery, a short or a malfunctioning device. I assume you charged the new battery before using it? Can you charge the new battery again.

I have replaced the battery in the unit with a new battery. within a couple of weeks the battery is dead. what would cause a drain on the battery?

Your problem is either that the battery is not being properly charged, OR that there is a circuit that is drawing power from the battery when the vehicle's key has been removed and all is supposed to be off.

If new battery and just a few weeks old it is eligible for warranty replacement. Get a new one and see what happens. If that one also goes dead then you certainly have an issue like I indicated before.

I have a 1997 BMW 528i that idles rough and now the check engine light came on. It idles rough, but when you press on the gas it runs smoothly. What could be the problem(s)? And the battery goes dead

Cars use the battery when they are not running. It is called parasitic drain. When the light comes on if you take it to a major autoparts stor like checker, advance or autozone, they can check it for free and tell you what the light means.

No Electrical power

Sounds like something is draining the battery.
Someone will need to charge the battery back up, then check the electrical system on the car for a short or something using power with the key off.

MY BATTERY IS DEAD ALTHO IT IS RELATIVELY NEW. A MECHANIC SAID IT WAS''LEAKING.'' WHAT DOES THAT MEAN AND HOW CAN IT BE FIXED??

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.
