'Battery charge fault / STOP' keep on appearing after several alternator changes. The alternator works well, it charges well.
Has anyone of you seen a problem like this? I'd like to know what to check now. Thank you in advance!

I have already tested 3 different alternators in the same car but the message was always the same.

Suggested Solution

you should get the battery checked as it may be the problem.a fully charged battery should give you 12.8 volts 12volts is a flat battery.also check earth leads and the positive lead for good connections.

Unfortunately you cant go back and edit or correct your posts on this site ,

" Crazy leading for battery "

Should have read ,

" crazy reading for battery "

If battery has weak / dud cells , the alternator will batter it's brains in trying to replace low charge .
