Hi there, this is my first post here - got this wagon 6 months ago and with COVID only beginning to drive it now so please forgive some newbie cluelessness.
I'm setting out the symptoms here at length to give you the full picture - any advice most welcome because the 12V electrics are completely dead at this stage.
I brought it to a dealer who says he doesn't know what's wrong, would take him a few days at dealer prices which would not be economic given age/value of vehicle so I'm trying to diagnose/fix it myself.
We bought the van in February, all electrics - lights, pump, shower etc working.
We got it home and all was working for a week or so when we showed it to people.
We didn't drive it anywhere for that week - it was parked in the yard.
After having it for a week my wife, her sister and kids stayed it in for a night to try it out.
They wanted to plug in an electric heater to the 220V supply so I hooked up the hookup lead for them, they plugged into the onboard 220V and all appeared to be working fine.
In the morning they woke up and everything was dead - lights, heater off etc
When they examined the hookup lead it had come loose or perhaps had never been plugged in properly.
Since that the 12V supply has not worked or is working very erratically.
The Cramer control panel will come on after a while plugged into the hookup lead and will show the engine battery at 14V, and the leisure battery at 0V or 0.1V.
Over many hours the leisure battery will gradually increase to 4-6-maybe 8 Volts but the pump never works when we try to switch it on.
The voltage reading on leisure battery never gets above 8V even after charging for 3 days.
The Burstner instruction manual says if the leisure battery reading falls below 8V to switch on the engine until it gets to 8V and then the hookup lead will take it from there to 12V. However, we've driven for hours at a time and the engine never seems to charge the leisure battery at all although when I measure the voltage of the leisure battery with a voltmeter it's at 12V.
Occasionally if we try to switch on the lights they will either come on momentarily and then die and it's back to square one with the control panel or they will come on for a few minutes and then die.
When the lights come momentarily and go off we can hear a click like a relay but we don't know which one or where.
I went out one night to lock up the van and when I opened the door the footwell light was on. Normally it never comes on.
The fridge will not work on 12 or 220V but will work on gas but to ignite the gas we have to connect the hookup lead.
We can light the gas heater [img][/img]- not sure if we need hookup lead to light that.
The red 12V on switch underneath one of the benches has two trip switches and half a dozen fuses - the trips have never tripped and the fuses are all intact.
I've checked as many fuses as I can find under the dash and under the hood and all are intact.
There are many relays and I don't know how to check them.
I came across a small linear block of 6 fuses (see pictures) near the engine battery which had fallen down near the engine and which has a black lead loose. There was a blown 25A fuse on this block which I replaced but didn't seem to fix anything. Am afraid to connect the loose black wire for fear or frying something. Have no idea if this block has anything to do with the 12V habitation system.
I have a wiring diagram which came with the camper I don't know if that's any use.
Losing my mind here - any advice welcome.
