Hello. Rapido 2019 Moho ducatto I have a Victron non isolated smart 30 amp B2B charger.
I notice that the engine battery level reduces the same as the leisure batts. I presumed the engine battery would remain holding its charge whilst using the on board 12 volt leisure batts. (The original leisure cables had 2 heavy reds to the + on the leisure batts, (these are now on the + bus bar) do you reckon I should remove one of them red cables from my bus bar as I think it's going back to engine battery??? I have a Victron smart shunt on the negative side.. Everything goes through the bus bars not direct to battery as per instructions. So the charger shows bulk charging and gets warm with green blink it is charging.
Second question. I have a flick switch on off in the remote switch of the block at the left front bottom of the b2b If I leave the flick switch in the charger on position when I shut the engine off the volts on engine battery show like 6 volts (see second photo)and throws the 20amp circuit breaker that connects from engine battery to the b2b. Why is that? If I remember to throw the remote flick switch to off then turn engine off the breaker does not trip out.
Final question on the Smart shunt app screen which figure shows me the amps that is going into leisure batts? I expected to read like 40 amps going in with the onboard factory charger and the new 30amp B2B.
Sorry for so many questions but I'm new to this. Thanks
