Hi, I've had the battery/alternator light comming on for some time now all you had to do after start was raise the revs slightly and it would go out. Engine turns over no problem and starts. The last couple of days I have had to keep the revs up for quite a while or drive away and then the warning would go. I've checked the battery (mercedes) don't know how old not 9years surely and the voltage is as follows:-
Before start 12.15v
After start 11.75v
After revs 13.80v
Does this indicate battery or regulator or alternator?
Anybody got any ideas before I start spending money on new parts?
Thanks for the help..
Michael.
