Hi all. I have a trailerable tug that we tow between FL and NY. Takes about 3 days. During the days while she is in tow, I want to keep the batteries charged up. There is always battery drainage from the CO detector, fridge, etc and I sleep on her at night while underway.
So, here is an idea. I'm thinking of running a lead from the truck's alternator back to the boat and allow the truck's alternator to charge the boat's battery banks. The alternator is running anyway and there shouldn't be much draw on the truck as I drive those 10 hours each day. I have accessory switches / connections under the hood that I could tie into on the truck side and I'm thinking the easiest place to tie into on the boat side would be at the alternator connection on the boat (single engine inboard).
Would this work? Are there any diodes or check valves I need to think about with this type installation? Really, just brainstorming right now so I'm open to all ideas.
