There's something about all this electrical issues that just doesn't add up to me, while I am a motor mechanic, I've been out of the trade for 30 years, I'm pretty good with electrics, but electronic cars, no so smart I'll admit...
1: If the battery is over 10.5 volts, the car will start, any other car that would be too low to start.
2: At 9.5 volts all the electrics still work, lights, console, central locking, windows, sunroof, tail gate, everything but the car wont start, and the electrics go a bit haywire (wipers going off dash lit up like a Christmas tree etc), but they do work...
3: Alternator is okay getting 14.5 volts from that all day long...
4: The batter is only holding 11.5 volts, so it's dying that's for sure...
I've never seen a car behave like this with a failing battery...
I'm starting to wonder if all the electronic issues I've had have been because of a dud battery?
The car has only traveled 25000 KM in 3.5 years thanks to covid, so I'm just thinking out loud here, maybe the battery was crap from new, or 12 months old when all the consoles started to fail... Guess I'll never know for sure...
