Hey all. I just bought an 87 373v and have a question about the breakers. It has the 2 breakers for the trolling motor. And 2 breakers for the main but they don’t seem to push to turn off. I used to have an 86 373v and those breakers would trip when pushed to turn them off. Just want to make sure there isn’t anything gonna drain on the batteries. Can I add a main shutoff for the hole system or is that crazy? Looking for opinions and ideas. Thanks yall
