I've been doing my Valence upgrade, along with all associated chargers etc in little momenst of time I've found over the last few weeks and decided to take the afternoon off work today and finally get it all completed. Now everything to do with the new electrical install has gone fine with Victron Smart battery protect, an Orion 30A to replace the Ctek, a Smart sense and my existing 100/20 Victron MPPT (I haven't got round to fitting the Victron mains charger in place of my existing one yet as I didn't have time and very rarely use it anyway) and the problem is not to do with this, hence me not adding it to the Valence thread.
Once I'd connected it all up I checked the interior lights worked, saw the control panel at the back light up and quickly opened the fridge door to make sure the light came on. Checked the status of all the Victron kit and everything was working and charging fine and the Valence was sitting at a healthy 13.2v. Even tested the inverter and it powered an LED worklight and then a Tassimo machine with only 0.2v drop. Very impressive and ready to put tthe seats back on, one final check...
Oh dear. Westfalias come with a control panel which displays the time and outside temperature, the status of the fresh and grey water tanks, and control the settings of the fridge and Eberspacher - and neither of the latter worked. Although the fridge light came on, the control panel seems to rely on its voltage reading to decide if it has enough power to run the system and it now thinks it has no power. There was an old shunt, which I took out and replaced with the shunt for the AliExpress coulomb meter (yes I was too tight to buy the BMV). I had just connected the 2 wires which came from the old one to ground, but when this happened I connected them to either side of the new shunt but still nothing
So all the stuff under the driver's seat is going to have to come out again so I can try and trace how I can convince the control panel that there is a leisure battery. Gutted as I thought I was 10 mins away from having it all back in and the van usable again and I don't know when I'll be able to find that much time again this side of Xmas. Here's what the control panel now looks like. I can't find a wiring diagram for it or the underseat connections for it anywhere. I don't see how it can be just a different shunt causing it, but if necessary I'll have to put it back and just manage without a SOC meter. I also don't understand why it's lost its outside temperature reading as well as its voltage readout, I connected all the wires that came out under the seat to the same battery connections they had before.
