We have a Multiplus 12/1600 in a campervan conversion, the van requires some welding. I know that if there is no AC input the ground relay is open, but I cant find a definitive answer on what the relay is doing when the Multi is switched off but still connected to the leisure batteries?
Simply disconnect ALL Connections to Multi, Battery and any Electrical Components before Welding ...
Yes, we can ask a welder to switch of a switch or rotate an isolator but not necessarily remove a chassis bond from a complex setup. Hence the question on the relay position.
Ground relay opens when MultiPlus switched off, even if still connected to the battery.
