Problem solved. I am on shore power and inverter usually buzzes a little all the time. Soooo I checked the batteries and had one post with some acid buildup. Checked that post and nut was not tight. Also next post was finger tight too. Checked voltage and it was 11.8. Cleaned both posts tightened them down and inverter began to hum. Hooked up auto battery charger and made sure all batts had correct water and we are good to go. I knew you all had all the knowledge so thanks a bunch for the help. Snugged all the nuts and will check the auto charger tonight along with getting another charge reading. Man at 38 degrees, it's cold out there. Be blessed wherever you are.
