Autosleeper sigma fuses blown (1 Viewer)

[Riverbankannie]

away with friends and their new to them camper.
After an evening of cards with us, they returned back to find a message fuse blown and no lights, but then message disappeared and lights came on. However happened a couple times more.
When switching on Trumatic heater this morning on to the ignition setting, heard clicker going then main control panel flashed fuses 2 through to 8 blown.

On EHU. at CAMC site
The fuse board is a PDU4M which has a plastic cover over the set of fuses.
Techniques for removing that please without breaking it.
Thanks

Can solve problem briefly by wriggling wires going into the PDU unit but only for a few seconds.
Have decided expert help needed.
Thanks

Sounds like some dry soldering and will need the panel off for a good checking of the joints...

Fuses don't 'unblow', so I guess the display is sensing a break/bad connection somewhere, and erroneously concluding that it's a fuse that's blown. That could be anything: a connector that's worked loose with vibration, a visit from our furry friends, the list is endless. Same with the fuses 2 through to 8. I presume since you haven't got the cover off you haven't actually checked the fuses yet.

We think fuses still working as a wriggling can bring on briefly so poor connection somewhere

I have nothing further to add to your woes, but Morrisons has an offer on for gloves at the moment !

Have fun with this one, it is all part of the charachter building

Thankfully it’s not ours!
I need to post the questions because (touch wood of which there is none to hand inside our van!) we have avoided such problems ourselves.
