Hi,
Got the message a couple of days ago so charged the battery with a Ctek charger and it fully charged the battery over 24 hours. Tried the car again and the message didn’t clear.
I connected a multimeter across the battery terminals and it read just over 12v, started the car and it dropped to 10.98 and then when back to just over 12v. As the load increased by switching on lights, heated windows, heater etc.. it dropped to 11v and occasionally into the late 10’s. Turning lights etc.. off and it went back to just over 12v.
At no point did the volts rise into 13v or 14v so does this indicate that the alternator is no longer working?
I was just going to replace the battery but having tested the volts I’m thinking it’s the alternator.
Any help would be appreciated. Thanks.
