Chassis battery won’t charge from converter

I have a 2000 Coachman Catalina 330 mbs and the Chasis battery is not being charged by the converter all of a sudden. I have had this coach for3 years and it has always kept all of the batteries charged when plugged in to shore power, but toward the end of last season I noticed that the chasis battery was not being maintained. The battery will charge from the altinator but will slowly drain down during periods of more than 3 weeks or so without running the coach, and the coach batteries are still being maintained by the converter. Owners manual says that use/store switch must be in use for chasis battery to charge from converter and when I press the switch to use I hear what sounds like a solenoid click but when I release the switch it click again which seems unusual to me. Any ideas are greatly appreciated and thanks in advance for your input.

This is why when I have friends that acquire a new coach, I try and get them to really learn how things work on them. The charging system(s) on RVs, varies greatly. Gas coaches do it a few different ways and diesels, the same. You may have something as simple as a fuse that's blown. The smartest item that many of us have purchased and learned to use with even modest knowledge, is a VOLT OHM METER. They can be a big help in checking many systems on these rolling Kleenex boxes on wheels.

To use them in battery checking is invaluable. They can tell you right off the bat, just about anything voltage related in batteries. Now, they can often tell you what's broke. Albeit certain other checks need to be made in order for that to take place. For instance, you pushed on a switch, made a potential "solenoid" click but, when you let off, it clicked again which, may or may not be your issue. Again, this is where it pays to learn about certain things on all of our coaches.

Sometimes looking things up in manuals is not the most entertaining way to spend an afternoon but, it sure can come in handy if and when a malfunction occurs. What I'm getting at is, if you have any manuals, on any of your electrical components, i.e. converter, converter/charger etc., they might lead you to test an item or two which, in most cases, takes only a minute or two. Then, if you're lucky, and you find a bad "solenoid" etc., a local trip to an RV supply or even an Auto parts store might be in order.
