Default problem when connected to shore power

I have a 2018 Roadtrek Zion With echo trek system all works good when dry camping but when I plug into shore power the dc voltage fluctuates anywhere between 13v to 14.9v and I hear a loud noise like relays opening and closing
any help would be appreciated.
Thanks Joe

remember when your plugged in the charger part of your inverter/charger/converter is working

After a few minutes tried to start the vehicle and it worked fine. driving situation were cold and wet. this is a brand new edge. Anybody knows what could cause such a thing. at a secure by dealership now awaiting analysis.

what is the timescale of the noises and voltage fluctuations?

My batter charger goes to the mid-14-volts about once a day (two days?) as part of a battery maintenance program... but it sounds like your issue might be on a much faster scale?

If you are plugging into the same place (home or campsite), you may have a reverse polarity (if you are using a surge protector which monitors this you will see a reverse polarity warning). Since you didn't describe this, I can assume this is a long shot guess.

The clicking noise might be the surge protector checking polarity and voltage every so often.

I know that most (all?) of the Roadtrek/Hymer Ecotrek systems need one (or both) Ecotreks turned on when the RV is connected to shore power, to prevent these DC voltage fluctuations. That is how my Hymer Aktiv works.

I missed diagnosed my problem when not connected to shore power the voltage I see is from the agm battery and when connected to shore power voltage fluctuate and hear the relays clicking, I found a RV dealer that will handle Roadtrek when they start producing new model and look after warranty they said my problem is that my lithium batteries have shut down and they have set up a appointment for me on 25th of this month. Dealer about 200 miles away which not too bad. Will post a update when problem is solved.
