    My last van was even worse than this one. I found out the hard way that the batteries were not charged at all via the tug. But the fridge did run off the house battery.

    After this issue is sorted, can we use this thread to post up some other general questions for discussion, and reverse engineering in regard to batteries and specifically the DIII/DIV charging systems, or shall we start a new thread.

    Hi unseenone, there is some discussion on this very subject on the thread linked to below.

    Just skip the garbage at the top of the page and then the rest of this thread is covering D3/D4 voltage operations.

    Your suggestion of starting a new thread is probably a better way to go.

    BTW, you should have a PM from me by tomorrow.

    Hi again mowog, these 3 way fridges are proving to be an absolute bloody nightmare.

    I’ve carried out a number of experiments and a single power supply cable just does not work, even when I tried 25mm2 twin cable, there was only a marginal improvement.

    The two cable set up you have, if it’s the correct size cable, is the best way to go.

    There are a number of options but the diagram below gives the best results for running a 3 way fridge and being able to charge your house batteries at the same time.
