I have a older global series aims 4000 watt inverter charger. It works fine under light load but shuts down between 20 and 30 percent load. Same with battery charge. it will only charge if batteries are almost fully charged. Can you help me to find what part needs to be changed on control board to fix this. I can put a jumper on small output transformer on control board and get more output but that does not help with battery charge
