Getting an alert ‘Charging System Service Now’ on a 2020 F250 Transit. This is the second time it has happened where it comes on and then goes away while continuing to drive. Wondering if anyone has had a similar 12v sytem fault? I have a 50amp battery to battery charger. Not sure if it faults due to alternator strain or something? House batteries are at 100% though and it’s the heavy duty alternator. Any experience or ideas are much appreciated!
