I have used the forum's search facility but haven't found an answer to my question, probably because it's so basic!
The Norman 23 I've just bought has a 1000w inverter and one 12v battery. I've only had the chance to visit my new boat once, and that was a "checking it over" visit. The battery is quite well-charged, reading about 12.4 volts.
I'm sorry not to have thought to take a photo of the inverter or maker a note of the make/model, but it has an on/off switch, three lights and two plug sockets. I think it may have a USB socket, too.
When I switch it on it beeps, the three lights come on for a second and then go off, and that's it. Nothing was plugged into it.
My basic question is - what's supposed to happen?
