    Part 3 of my answer:
    There are options that are hardwired and out of site. If the previous owner installed one, you could get a voltage meter and when you are plugged into shore power the reading at the jump posts under the hood would read over 13 volts. if that is the case then you should be good to go unless the MB battery is dead and not chargeable.

    I am camping now and have a good internet connection. I will check back here and my email if I didnt answer your question or you have any more.

    Good luck.

    Part 2 of my answer.
    A battery Tender or trickle charger may take a long time (24-48 hrs)to get your starting battery back strong enough to start the Sprinter again if it isnt too far drained and dead. If you have a regular battery charger that might be a better option now and then a trickle charger to maintain the MB battery from now on. If you are able you could take the battery out and get an auto parts store to bench test it to see if it is still good. They may be able to test it without pulling it if you can get it jump started. If you already dont know the MB battery is under the drivers feet but there are jump terminals under the hood. These jump terminals can also be used to charge the MB battery if your charger doesnt have the 12v plug for the outlet under the cupholders.

    No Bother. I can imagine not having a cup in the morning and I would have done the same thing. My answer exceeds the limit here on the forum so i am going to cut and paste into a few replies.

    Part 1:
    If you plug into shore power at home with a regular household outlet it will charge the house or coach battery but not the starter battery as it was wired from Jayco. I use a Battery Tender plugged into the outlet under the dinette and into the MB 12v outlet under the cupholders in the cab. This 12v outlet is always hot so it is still connected to the starting battery when the ignition is off.

    Hi Pfflyer
    Sorry to bother you privately. I lost power in our home this morning. So I decided to go out to “Millie” our 2016 Melbourne 24k to use the coffee maker. Got out there and the generator would not start. So I tried starting the rig and the familiar “click,click” of a dead battery. We have only had Millie 2 months and she is my first. I searched for dead battery in search engine. I am not clear the battery scheme for these machines. Power should be back on later today at the house. Can I plug in my shore power and will the batteries re charge or do I have to look for new batteries I ask you because I think you have the same rig.
    Thanks for any help you can offer n
