My auxiliary battery when starting shows hat it is malfunctioning. We only drive it 1 day out of a week it is a SLK300 2016. In the past I would just restart the motor after approx. 30 sec. and it would go away. Now it is no longer going away. I am now trickle charging the main battery and see if I start the car up after the main battery is fully charge to see if the Axillary battery will charge as well. What can I do?
