Quick update on my charging issue. I replaced the Intellitec Isolator Relay Delay (http://www.nwrvsupply.com/product/00-00629-120.html), which is located just to the rear of the stairs, under the coach. It basically senses whenever the generator and/or the coach alternator is producing X amount of voltage. It then trips the solenoid which is located right next to it to allow the batteries to begin charging.
Anyhow, aside from the Xantrex monitor showing me that the voltage would not increase whenever the gen or engine was running, I got under the coach and listened for the solenoid to trip when they were; it never did. I confirmed that the solenoid was functioning by having the wife press the "Emergency Start" switch located next to the steering wheel; it did.
I replaced the isolator relay delay module (see link above) and it fixed my charging problem. As RobbieH pointed out, there are several things that can cause charging issues (or appearing to not be charging), so this is just another to add to the list.

About half-way through a camping trip this past weekend, I started having a house battery charging issue. When I run the generator, it powers all of the coach, but doesn't charge the house batteries. When I run the engine, it no longer charges the house batteries either. The Xantrex display panel voltage doesn't increase after the gen or engine are turned on.
Its currently pouring raining here, so I haven't tried plugging into shore power to see if that will charge them. I'll try that tomorrow.
Has anyone else had this happen? I've done some searches and it sounds like the battery isolator relay (bi-directional isolator relay or trombatta?) might be bad. That said, I have no idea where these are located on mine (2014 33SW).
Thanks,
