  2. I recently bought a new boat and noticed some electrolysis on the minn kota trolling motor. The trolling motor is the only think wired to the trolling motor batteries. Everything else is wired to the 12v cranking battery. I’ve been finding some conflicting information online. Do I need to have a common ground between the trolling motor system and the cranking battery? Or should they stay isolated? Not sure if it matters, but all 3 batteries are wired to a Bass Pro Shops 3 bank charger. Thanks for your help.
