Trying to convert house batteries from two 12v to four 6v. Got everything done and some how mis-wired four batteries(changed how they were oriented) did'nt pay close attention. My bad, I'm getting old. Found this out when I turned everything back on and inverter display showed 11.7v and E02 error code(low volts). So I first plugged in to shore power, no change on display. I then started the engine. Display went to 15.2-16.4! Yikes! Turned engine off, went to battery compartment and before I could open the door I could smell burning!One of the batteries on fire. Put out fire, shut everything off. Couple of the cables too hot to touch. Replaced battery, checked other three. Rewired. Now still 11.7-8v on display. start engine display does not change(normally shows 14.2v) and does not change when plugged in to shore power(normally 13.6). What have I done wrong or what have I damaged? 110v appliances/AC work plugged in to shore, 12v lights, radio,fans etc work. Nothing seems to charge to house batteries. Now have external charger connected to see if can get 12.2-4 volts. why are'nt they charging on shore power or engine alternator? Help is appreciated
