Battery Light Coming On

[ooo000ooo]

under acceleration, belt is still there but showing signs of cracking,no squealing or any other problems although the missus reckoned the car was vibrating badly reversing out of a parking space yesterday? Seems to drive ok today in the quick run i had up the road and back.

Car is a 2004 alhambra tdi.

 

TIA

Check the Alternator

[ooo000ooo]

after a bit of a run on sunday which warmed it through properly the light has stayed off, hopefully it was just a bit of damp got in as the car was parked somewhere more open to the elements overnight. I'm going to spray a bit of wd40 round the electrics and try a new alternator belt when i get a chance and hopefully that'll cure it permanently.

Check the battery - how old is it?

If the battery voltage is low due to it's age then the alternator will be fairly loaded after you've managed to start the engine.

I've generally found battery life to be 5 years although I know some will say theirs is older.

If you can use a voltmeter then you can see what the condition is quite simply - before you start the engine it should be around 12.5 - 13 volts, after you've started the engine it should go up to about 13.5 volts at least to actually charge the battery.

Check out some other threads about batteries nd alternators - might be helpful.
