My battery light just came on, so does that mean the battery is low? Or do I have to fix/replace the electrical system/battery cables?

Its more likely your alternator gone bad! you if you remove the alternator people at advance auto parts or autozone can test it, when you buy a new alternator you will have to trade in your old alternator to save on the deposit..

You need to have the charging system checked to see if it is charging properly,it could be charging below the minimum voltage required to keep the light off,you could have a charging system problem that needs to be fixed.

Head lights on 02 cavalier low beam not working


Headlamps
The headlamps are operated when the driver places the headlamp switch in the HEADLAMP position. The LT HDLP and RT HDLP fuse in the IP fuse block, supply battery positive voltage to both the left and right headlamps. The low beam and high beam circuits continue to the headlamp switch. Depending on the position of the dimmer switch, either the low or high beam circuit will now have a path to ground. Ground is provided at G204. The low beam and high beam circuits also provide the body control module (BCM) with both low and high beam inputs. The headlamp switch includes the dimmer and the flash-to-pass switch.
If the headlight switch is left in the HEADLAMP position, the headlights will remain on until turned off or the battery runs dead.

The ground under the battery has nothing to do with the headlamps . G-204

It illuminates signs in dushboard.what could be the problems


first check your battery and cables... a dying battery and/ or corroded, loose cables may be the cause all those problems

If you don't have the owner's manual, you can get a PDF file of it from a USA ford website: Google search 2005 ford focus owners manual

The battery light means bad battery, alternator, or wires

Oil light means low oil level, bad oil sensor or bad wire to sensor

Abs light, check brakes or wiring to speed sensors or abs computer

Orange check engine light, a sensor or other electrical part has failed or wire broken to that sensor. You will need an obd2 scanner to find out trouble codes!

But, if ALL OF THE LIGHTS ARE ON while car is running, you really need to check and make sure the battery and charging system is OK FIRST

My battery light and oil temp light stays on in my mazda 1998 MPV


The battery light is usually an indicator of a failed alternator or bad cables causing low power to your electrical system. Without it, your car will run off of battery power until it is discharged and then shut down. Check all connections and test the alternator. If you dont have the facilities to do so, most auto parts chain stores can do it for you right in the parking lot.
As for the oil temp light, this is only a cause for concern if its happening with the vehicle at full operating temperature. If its steady on with a cold engine, then just the sensor is bad. Now....if its an oil "pressure" light, thats a completely different story. Do not run the engine until its sorted out. I have never owned a Mazda, so im not 100% on exactly what the light means, but its unusual to have an oil "temp" light. Is your serpentine belt intact?

Battery draining overnight,replaced with new battery now starting


Disconnect any one of the cable from battery (either + or - ) and in series with battery connect a 12v bulb of low wattage say 5w or 10w. By connecting in series I mean one wire of bulb goes to disconnected battery cable and the other wire to the terminal of battery from where you disconnected the cable.

Now observe the filament of bulb, if it glows then your battery is draining due to short in your vehicle electrical system. You need to locate this short circuit and fix it, otherwise your new battery would also drain.

Let us know what you found out.

The battery is run down too low. When the light came on, alternator stopped working- the vehicle ran off the battery, until the lights and other electricals ran the battery down too low.
Recharge the battery, and have the alternator tested. It will probably need replacing. If you bring it into a parts store, they will test it for free.

My 2001 ford focus would not start a couple days ago the person that looked at it said it was the cable that connects to the battery terminal .Now it has dont it again this time it want jump start all the...


You need to fix or replace the cable and then charge the battery with a charger. Jump starting with a dead Battery will sometimes trigger the Security system and it will prevent starting.

Most likely your Battery continued to run down because the charging system could not get the electric back into the Battery. So as you drove, the Battery was getting weaker because of the bad connection of the cable.

Charge the Battery, fix the cable, and then go to Autozone or Oreillys for a free scan or charging system test. They will hook up testing equipment and find out if anything needs replacing. The testing is free.

Upon startup engine idles rough then speeds up and returns to normal idle .After a couple of minutes the volt light comes on then no power then a complete shut down.Starts back up for a while then shuts...


OK, the volt light means that the alternator is not charging the battery. It could mean the battery is shorted out, or the battery is bad or low on charge due to an alternator not charging.

Replace the Alternator and battery as indicated by standard voltage output tests under load.

The computer in the car will not operate the engine properly on low voltage.

Fixing the charging system, may resolve the rough idle (meaning that it may be trying to relearn after data was erased by low voltage of the battery), and the speed up.


Try the charging system first, and once that is repaired, reevaluate the engine driveability and speed and idle smoothness, after it relearns.

Good luck on this repair.

2000 lincoln ls i got a trouble code p1633 (KAM)voltage to low


P1633 means KAM (Keep Alive Memory ) Voltage too low. the KAM is caused by low battery voltage and you replace the battery.When you replace the battery the KAM loses Memory and the problems resulting in what you are experiencing now.When replacing a new battery, reconnect the Positive cable first.And use a trickle battery charger set low to the cables before disconnectng the battery . this will keep the voltage to the ECM powered with enough voltage. All you can do now is make the computer relearn the way it should run. Disconnect the negative cable from the battery, wait a while 20 seconds or so. then reconnect the cable. I do not know if this is a temporary fix or not but it should re-program the computer.
