Hi everyone,
2012 Megane 1.6 Dci 130 Gt Line.
Ok so I have had my alternator replaced this week due to it going noisy and eventually failing on me.
Went to collect it on Wednesday evening and drove away, next thing the dashboard flashes up 'Battery Charging Fault' along with the red spanner. Ten seconds later it goes off and the dashboard says 'Stop Start Activated'.
Anyway this kept happening and has done for the rest of the week and I'm also getting the odd error message saying 'check stop start'.
In the meantime I went back to the mechanic to discuss the issue and he said he would speak to his auto electrician contact about it.
He also said he had tested the alternator output and it was charging fine.
So he phones me up and said the auto electrician said maybe swap the battery as it has probably been killed when the alternator failed.
Cue to today, I fitted a brand new Yuasa battery and followed the correct removal and fitting procedures.
Goes for a long drive and had the same fault again about 20 times.
Tested battery with and without engine running and seems to be fine. Although I checked again just now under load with engine running and I was only getting a reading of 12.2V.
My mechanic is actually a vauxhall specialist and I have been going to him ever since I previously owned a few Vauxhall's so Renaults are probably not his strong point and I know he only uses a snap on tools diagnostic machine.
I have seen a few mentions of the 5amp fuse behind the battery box and wondered if it is worth checking that, although part of me thinks it has to be something like the alternator to battery wire.
I was intending on changing the battery anyway before the alternator failed as I've owned the car for 4 years and the stop start only kicked in maybe 3 times.
Any help or advice with this would be much appreciated please.
Images are readings from when I fitted the new battery earlier.
