We have had to jump start the MH a several times after is has been parked for a few days in store or use. The only time the the engine turns over after being unused for a several days is if we are plugged into electricity. The house batteries and the engine battery seem to be connected.

I am including our battery voltage test/log results.

7/28 all batteries fully charged. We disconnected the MH from power.

7/29 house batteries 12.3 volts and engine battery 12.2 volts.

7/30 house batteries 11.75 volts and engine battery 11.75 volts.

7/31 house batteries 11.47 volts and engine battery 11.46 volts.

8/1 With the engine battery disconnected there is still voltage on the engine battery cables.

We are very concerned about the battery issue. We have taken our 2015 ACE 27.1 in several times for service regarding the batteries/other repairs and it has been out of service for long periods of time. A new battery control center was installed and we are still having the same issues.

And we still have the same battery problems.

How can the engine battery be separated from the house batteries?

We love our ACE but cannot live with the battery issue. We do a lot of primitive camping and cannot trust we will be able to start the generator(to recharge the batteries) or to start the engine.

Should the house battery and the engine battery be the same voltage?

Any assistance you can give us will be greatly appreciated.

Thank you,
