    My Compass Avantgarde has a battery status indicator, which doubles as a fresh water tank level indicator. There is also an Aux/Veh battery switch, which of course I always have in the Aux position normally. The handbook says the battery status indicator shows the status of the battery selected, but I have noticed that when switching between batteries the voltage indicated doesn't change - even after a couple of nights away recently off EHU when the voltage had dropped to just below 13v on the Aux battery (as you would expect) switching to Veh battery it didn't move, staying at just under 13v.

    Have I a problem? My concern is that both batteries are draining.

    I think you`ll find that the dual water level/battery status guage only corresponds to habitation battery and not the vehicle battery. The Aux/Veh switch only switches the charger between the two when on mains hook-up :Wink:

    Unless I'm misreading it, that's not what the handbook says.

    Think that is wrong, the hookup charger never charges the veh battery, the switch only let's you use the van battery as an emergency thing if your hab battery runs out although the gauge does show the volts of either, ours is nearly always way better on veh battery, after a bit of use but when we park up they are usually the same.
    Hth, only my interpretation :thumb:

    We have a series of Red, Amber and Green lights which do the same thing and they give an indication of charge level in either battery, depending upon which way the rocker switch is set...

    That's more or less what I found when we had our Autoquest. The one time the switch was inadvertently set to Veh it didn't half drain it fast :Smile:

    Not on the Compass/Elddis range. The starter battery is not charged from EHU using standard wiring. I installed a Battery Charge Manager in ours to overcome that.

    Obviously differences in Vans. My AS works as Crimbo says, but I know that is not the norm.

    if the switch brings the engine battery into use then it will also charge it.
    The only way it wouldnt is if the charger was connected directly to the hab battery....which it isnt, it is connected to the centre contacts of the said switch either directly or indirectly.

    opp5sorry, i stand corrected. I don`t know wether i`m right or wrong now. All i do now is that my charger set-up says it will charge whichever battery the Veh/hab switch is set at.

    No it doesn't, if you are on hookup there is no need to charge the veh battery as you would not be useing it or for that matter the hab battery either, but if you are off hookup you would run your hab battery down and could in theory use your veh battery in emergency but wouldn't be charging either.

    That was our experience. The time that the switch was knocked by mistake we were on hook-up and the starter battery ran down rather than being charged - I had to get a jump start off a tugger :Eek!::Eeek:

    agreed, you dont even need a battery fitted on hookup but if you can use the engine battery off hookup then its wired in such a way it can charge on hookup.

    Its still powering up the 12v circuit which includes the charger wiring.

    So do Burstner - and such that the solar panel charges both when wired through the Elektroblock unit :thumb:

    No it isn't, don't know how it's wired but it definitely doesn't charge the veh battery wherever the switch is, I have seen in other threads a while back where someone had a normal battery charger plugged into the 240 plug in the van while on hookup connected to the veh battery and then charging both up from hookup
