Update

Problem solved

I have a Schaudt LRM 1218 solar charger fitted which has 2 red wires coming out. One had come out and as it's not easily seen I only discovered it after deciding the fridge had nothing wrong with it and started at battery checking all connections

Thanks to Martin Bushnell at A & N Caravans for his invaluable advice
