I was doing a few jobs on my Lunar today on the storage yard with the EHU connected to a generator. I've been fretting a bit because the voltage on the control panel was only reading 12.8V. Normally it shows about 14 on EHU. I'm now paranoid about a possible issue with the charger. I was only using a socket for tools and hoover, it only occurred to me on the way home that I hadn't turned any of the master switches on. There are four switches in total, I know that one is for the water pump, one for the space heater and one for the water heater, which leaves one. I'm sure I vaguely recall during the handover the dealer saying one of them is for the battery charger... I suppose the only way to know for certain is to go over there again tomorrow and check but I'm trying to avoid another trip at 45 mins each way, plus faffing around with gates etc and put my mind at rest at the same time...
