My turbo diesel couple of weeks ago delivered a couple of flat batteries. I replaced these and the installer said that the charge rate when at idle is sitting on about 12.9v when loaded with lights and aircon. That isn’t right I was advised.
My mechanic said alternator probably on way out. ( the car has done 127k) so I replaced the alternator.
Problem is still there. At idle the voltage drops from 14ish Volts to about 12.9 when lights on etc.
Does this sound right , I would have thought Brand new alternator would be sitting at about 13.5-14 at idle.
Or have a replaced the alternator for nothing as it’s a diode or regulator that’s failed.
Anyone come across similar problem?.
