tbourner Posted July 25, 2009 Share Posted July 25, 2009 2005 Vauxhall Corsa 1.2 SXi. When starting it doesn't turn over 'quickly', it always starts on the second turn of the engine but cranking sounds a bit slow, also when stationary and dry steering the headlights dim, I wouldn't say they dim a lot but definitely noticable. Is this likely to be the battery going? Or the alternator? Or just normal? Quote Link to comment Share on other sites More sharing options...
Havard Posted July 25, 2009 Share Posted July 25, 2009 Sounds like you have a short somewhere or the battery is fubar. Is it the original battery?? H. Quote Link to comment Share on other sites More sharing options...
tbourner Posted July 25, 2009 Author Share Posted July 25, 2009 No idea, I guess so though. It's probably due a replacement anyway. Car only bought last week with no warranty, I guess I can get it sorted under sale of goods act? Quote Link to comment Share on other sites More sharing options...
movistar Posted July 25, 2009 Share Posted July 25, 2009 Lights would look normal while the engine is running as the alternator would be putting power to the battery...if they are not then the alternator has probably had it. so if the alternator has not been charging the battery then this is why it is slow to turn over...using the car has also been slowly taking all the charge/power from the battery hence draining it. It may not be necessary to replace the battery if its not been totally discharged for any long period of time. replace the battery if the alternator seem so be charging, as it might have a dead cell. Good luck! Quote Link to comment Share on other sites More sharing options...
tbourner Posted July 25, 2009 Author Share Posted July 25, 2009 How do garages check for battery or alternator failure? Surely my charging warning light would have come on the dash if the alternator was shot? Quote Link to comment Share on other sites More sharing options...
movistar Posted July 25, 2009 Share Posted July 25, 2009 With there test equipment of course...and light may not come on as its a possibility it still could be charging but just not enough. Vauxhalls would probably use tech 2 test equipment snap-on scanner, a snap-on alternator tester or a multi meter.....so on .... sounds like your best taking it to a mechanic ;-) Quote Link to comment Share on other sites More sharing options...
