Electrical

Thanks for the help with water pump question. Now I have a new one. The porch light, compartment lights and one set of indoor lights do not come on. However, today for a short time the porch light turned on using switch. Now it does not work again. On the panel with the battery, porch and step switches, the battery light is on, and it wasn't on earlier. Any ideas on what is going on? The batteries on monitor panel says batteries are charging. We are hooked up to shore power.
