Battery charging Voltage
Posted: Tue Aug 12, 2014 8:50 am
Hi,
my sons just brought a Corsa 2005 sxi
It failed to start the other day, flat battery ? RAC guy said it was a faulty alternator. When I measured the charging voltage across the battery it was about 14 .1 V but fluctuated down to 12 and below !. I wonder if this is a sign of poor earth, bad connections , measured the alternator casing to battery ground .02V. Battery indicator light is on and goes off when started
Any advice would be much appreciated
Also If I disconnect the battery will I lose radio , as I've not got the code for it
Kind regards
