Ok,
@Drover @Boots in Action I have 12.72v at the battery terminals, I have 12.72v at the terminal from the battery input on the Setec, I have no increase in voltage to the battery when 240v is on but the lights work when the 240v is on but not when it is off so seems not to be working on the battery.
The only light on the front panel is the green 240v main connection light, the battery orange and the fault red do not come on.
The van was connected to mains since NSW locked down as the home boss was using it as her office away from the kids home schooling. About 3-4 plus weeks ago (before I started this chat) all the power went off in the van, but no trip switches had gone off (this she informed me just now was while we had a big thunderstorm). I unplugged it checked the fuses etc and plugged back in and it worked again but since this the battery has not run anything in the van.
So when the kids went back to school and she moved her office back into the house I started looking into it as I could not pull up the seats etc while the home boss was in there.
Sorry if I have been confusing, so basically the battery is not being charged while on 240V and it is not feeding back into the 12v system when not on 240V and we free camp quite a bit so need it to work. I do not need anything that requires 240v power when off grid (I have a 30year old Honda 650v genset inherited from my father in-law) so do not need an inverter just a converter Jayco advised me over the phone to get the Projecta PM100J or PM235J as a replacement so minimum of $430 to replace although RV parts express has it for less just if I can avoid a $400 outlay as you say
@Boots in Action to find the same problem haunts me!
Hope that is clearer?
