Mercury 250 4 stroke # 2B594282. How can I test to see if my motor is charging my starting battery while running?? No I don't have vessel view but I am just watching my volt gauge on the boat and it doesn't seem to move when I am running. I noticed a couple times that when I adjusted the trim while running I got a low voltage warning on my Solix unit and also when I started the motor. It was showing 10.9 low voltage warning on my Solix I have a new X2 31 series battery which was fully charged when I left. I was only out for 6 hours. Never turned on the livewells and running two Solix 12's. I made a few runs during the day probably about 15 minutes of run time. When I got home before charging the battery I put a volt meter on the battery and it read 11.98. The voltage supply on solix showed 11.3 at the same time the volt meter would show 11.98. Is that about normal should I be worried its not charging? Sorry if this is confusing! Thanks
