The battery switch, on the inside wall panel, must be on before you plug into shore power for the coach battery to charge.

My owners manual for the 2006 190 just says battery charging is automatic for both shore power and the generator. Nothing about turning on the master switch before connecting shore power. In fact the 12v service light at the monitor panel comes on automatically when plugged in and you cannot turn it off.
I checked the tripplite website for the 750UL and they state charging is automatic.
I took the advice and tried switching 12v power on before plugging in and got the same results. The inverter did show a charge voltage of 14v. but still 11 volts at the battery.

I think I found the confusion. The owners manual refers to a completely discharged battery shutting down the charging section of the inverter. Then the battery will not charge when connecting to shore power.
This is indicated as either completely dark monitor panel or as a flashing red LED on the inverter.
I my case I have full 12v service as indicated on the monitor panel and as referred to by the tripplite troubleshooting steps of having 14v (charging voltage)at the inverter battery connection.

They may have changed the way the battery switch works when Rt went to an inverter/charger, I know most, if not all the older Rt's with converters, have to have the battery switch on before plugging in to shore power. The red light will still comes on, but the coach battery will not charge.

I believe I found the issue. As I said earlier, I found it strange the inverter was connected on the right side of the relay versus the left side. I went ahead and reconnected as the schematic showed.
Testing the shore power, I had 14v at the inverter. Checked the batteries and they were at 14v. as soon as the batteries were charged, the inverter voltage dropped to 2v. The batteries showed a full charge of 13.53v.
I discharged the batteries 25% and tested again with the generator. Again I had a good 14v both at the inverter and the batteries, dropping to 2v and the batteries at 13.53v.
I tested all 12v and 120v power draws. Everything looks good.
Thank you so much for your input and suggestions.

Uh-oh..... I'm reading this thread and Handbasket posted with this in his comments: "I think by '06, they'd quit using the cheap single stage battery-boiler charger, ....".
I have a 3-months-old-to-me '94 Roadtrek and I've been in the habit of leaving it plugged to house power all the time setting in my driveway.
Am I damaging the battery and just haven't realized it yet? I assumed from the literature that the charger/converter was cutting the charging power on/off based on the state of the battery. Not exactly a "smart-charger" process but I assumed it was ok.
Does anyone know if I'm doing the wrong thing by keeping it hooked up?

You need to check the water in the batteries, probably once a week, with a single stage converter/charger if charging the batteries for extended periods of time, and at least once a month otherwise . Single stage converter/charger is much harder on the batteries than say a 3 stage conver/charger, with charge wizard, from a company like Progressive Dynamics.
Lots of info about this in the archives, you may want to do a search.
