I posted a question on here on 6-9-22 about how to wire and charge a battery for a trailer winch. I got a lot of good information and lots of good answers. One of my major concerns was charging the trailer battery while the truck is being driven and towing the trailer. What I did was this; I ordered a solid state battery isolater (~$30)from that big store that begins with the letter A. It is used with some motor homes and such and is designed to start charging the auxilary battery when the cranking battery reaches a voltage of ~14.2 and then when the cranking battery voltage drops to ~12.5 it disconnects the extra battery charging circuit so the cranking battery does not get drained. Thanks again everyone for helping with this. Gene Davis
