Interesting what you say about the smart alternator, I didn’t know that. I’m by no means a mechanic or auto electrician, literally what’s under the bonnet runs it and put petrol in the hole in the side to make sure it runs lol
It’s never cut out while driving, issue is random lengths of run time in parking mode, it’s not very consistent, and at 12.5v it cut off as soon as I killed the ignition, but others haven’t had that experience. I run it generally at 12v before it automatically cuts off in parking mode, but then I randomly get a message about the starter battery discharging due to external electronic devices when I start the engine. Doesn’t happen every time either.
