Thank you for this helpful article. I am experiencing a new issue with my SMB pop-top motors. Previously, my isolator was connected to my alternator. Now my isolator is connected directly to my van battery. Ever since it was connected to my van battery, the only way I can pop the top or use the lights in the pop-top is if I have the van on. Those features no longer work when the van is off like they used to. Any recommendations for this issue?
