Good battery but no power

[Jowersgd]

I have a 2020 Freedom 192 with two batteries. Battery 1 is working fine. Battery 2 is fully charged (put it on a charger this morning to be sure), however, when I turn the selector switch to battery 2 I have no power at all. It was working fine a week ago. I did not remove or disconnect battery 2 until this happened. I did, however, disconnect battery 1 for unrelated reasons before this began. Any thoughts as to what is going on?

thanks

Since it happened after you disconnected Batt 1, the first step is to retrace what you did. Look for a wire that wasn't put back on #1, such as a shared ground.

you may have missed a black jumper cable that connects the two negative terminals of both batteries together.

That’s exactly what I did. Thanks for the help!
