If anyone has a similar problem with the house batteries not charging from the engine alternator a piece of advice. Before you spend the money and effort to replace the pressure switch make sure it is plugged in. The 2 wires coming from the pressure switch go into a wire bundle where there are 2 connectors. Each wire{blue and green} has an individual plug that mates to the corresponding color in the pack. I went to all the effort to replace the switch then I found out at the end that all I had to do was plug it in.
