Hi looking for a bit of advice.
Battery light is coming on about a minute after starting my Viano. 2008 model. W639.
A volt meter in the cigarette lighter shows it's charging the battery at about 14.6 v and my ring smart battery charger also gives it the thumbs up. The garage is stumped I. E. The signal wire appears to have continuity etc. I have replaced the 2008 battery but the fault persists.
Is there a way to check whether it's an alternator fault without fitting a new one. I. E. Mimic the signal the alternator should send when it's charging to see if that switches the light off? I'm not electrically minded so idiots guide patronising tone welcome!
