Control Panel Readings

[5andy]

We are having a couple of problems with the Control Panel readings of our Dethleffs Globebus Camp T1. Don’t think they are connected, but anything I know is taken from a less than helpful manual. Firstly, when I check the readings for the battery when the MH is connected to the mains the readings are absolutely fine and the battery charges. When I unplug from the mains I get no reading for the vehicle battery and, I’m not certain and probably wrong, but I don’t think the vehicle battery is charging from the solar panels. I’m thinking that it’s a fuse but I cannot work out where it would be and I haven’t found much of a clue in the manuals or from the internet. Can anyone suggest what the problem might be and if it’s a fuse where it might be located. It’s still under warranty but if it’s just a fuse I would just fix it obviously.

Second issue, whilst the fresh water reading seems reasonably accurate the waste water is shows 100% whether it is empty or full. No idea what’s going on there but any suggestions gratefully received.

I should say that the readings for the leisure batteries seem to reflect what I would expect.
In case it’s useful I attach photo of control panel.

Cheers Sandy

Have you checked under the front seats?

Yes. I should have said. Nothing about battery. Already had to change the electric pump fuse there.

Try removing and cleaning your waste tank level indicator, or rubbing the 4 metal rods in situ with something like the back of a kitchen sponge (the green bit).

As for the voltage reading, I would check with a meter that the engine battery is getting charged. It sounds more lie a break in the wiring circuit. Sometimes turning the panel off for 30 seconds and powering it up again might reset it.

Thanks for your reply. I’ll give that a go. TBH I’m not sure how to access inside of the grey water tank, it was so much easier in the last Motorhome. I’ll nave a look at the manual.

Mine has a screw off lid/sump to get access, similar to the lid on a fresh tank.

I’ll a look in the daylight tomorrow. Thanks.

No idea why the VB only shows when on EHU, but as for charging, are you sure the solar is actually wired to charge it? The dealer who fitted our solar only connected it to LB!

Thanks for question Colin. I made an assumption that it would be, in reality I have no idea if it is. Having said that it’s a bit of a missed opportunity if it isn’t. My last Motorhome certainly was. I wouldn’t know how to start finding this out. The time has come I think to ask the dealer.
