Check voltage across battery with engine running and engine off ,check with a automotive multimeter as it may just be a faulty dial ,if voltage rises to 14.7 volts or there abouts with engine at 2000 rpm then all is fine ,if low then it could be a problem with the ECU as this controls the output on a newer car like this and if its not working correctly then its a expensive dealer job but the alternator can be converted back to battery sensed charging

Brake light& battery light keeps coming on now car won't start


Anytime the battery light on the dash comes on is an indicator of the alternator not charging, resulting in a dead battery. Low voltage will cause other warning lights to come on as well. Replace the alternator and fully charge the battery before running the engine, to avoid full field condition with the new alternator ( overheating).

95 Cadillac sts will not hold charge,new battery new alternator?


What's the voltage reading at the battery with the engine running ? 13 to 14.1 volts ? If not, it's not charging .Sounds to me like it's not charging ! Is there battery voltage at the heavier gage wire on the back of the alternator ? Does the battery symbol light on the dash work ?

We changed the alternator and now we have a red light in the dash for battery


the red warning light comes on when there is low charging voltage test for charging voltage between the alternator and battery should be roughly 14 volts

The battery light has come on in car and the windows and central locking have stopped working


The battery warning light comes on because the output voltage of the engine alternator (dynamo) has fallen below the voltage of the battery, this turns the alternator into a ground and the light for the battery turns on in the dash. The other electrical problems are likely symptoms of the low system voltage problem caused by the low alternator output voltage.

My mercedez benz clk 430 wont start . in the dash it says batttery/alternator. what is the problem?


Test battery charge, jump the battery to start and check battery charge, sound like a alternator or voltageregulator wrong there.

Dash says battery not charging


Alternator is what charges the battery. The alternator isn't putting out enough of amps to charge your battery and you will get a light or gauge reading that the voltage is low.

Your alternator is on the way out,replace with new or rebuilt. you can remove alternator and have it bench tested to be sure.

My 03 x type jag wont even try to turn over? Dash lights are fine but windows, mirrors and starter dead! All the dash lights and monitor and radio work but wont even tryto start? Transmittion wont come out...


Sounds like all of the high drain devices are disabled due to a weak battery. You are still getting dash lights and radio because they are very low drain devices. Try charging the battery to test for now. It could be a failing battery, or your alternator and or voltage regulator could be going out and not charging the system. But first, try to charge the battery, and see if you can start it, if you can, let it run for at least 10 minutes. If your alternator/VR is going out or is already out, you should have a guage, or idiot light telling you that you have low voltage. If its a light, you should see a red battery lit up on the dash, if its a guage, it should be directly in the middle +/- a little. If you are able to run the vehicle for a while with no light coming on, or guage showing low voltage, its safe to say you drained the battery, or it is failing. If its a few years old or more, i'd go ahead and replace it. Hope this helps :)

Causes of low battery voltage and solution


i had the same problem with my dash saying battery voltage low and the problem was my alternator. took it to the dealership and it cost me $400.00 to replace a connector on the alternator because for my year car a (2002) they don't replace entire alternator.

Very first thing is to check the battery and alternator are o.k. If battery voltage is low the ecu will not allow the starter motor to operate. it may be that the central locking is just draining the battery enough when you open the car that it won't start, then after a short period the battery recovers and so the car starts. low battery voltage can also effect the engine management.
