No 12 volt house power when disconnected from shore power. Everything works when plugged in to power. What should I check first?

I'm in search of the most economical way to replace a hot water/glycol pump in the Oasis DM12 or similar distribution module. This system uses the ITR Oasis burner to heat the water/glycol fluid to circulate through 2 separate loops for hydronic heating as well as for hot water in the coach. I believe it is supplemented by the engines heat when it is running. My quest is to find a supplier for the 2 (maybe 3) pumps that are incorporated in the DM12 distribution module. When searching for the GRI (Gorman-Rupp) INTG2-103 pump, I come up with zilch. Gorman-Rupp has a new series INT3 pump on their website, but not knowing how to purchase one, I'm looking all over the web for a source. A bit of my findings was a replacement motor for $494 via Newmar vs. $295-from ITR. Still these prices are extreme, in my opinion. Anyone with knowledge of replacement or repairing these pumps is welcome to advise me, as this is a part I can probably live without, since I'm in a warmer part of the country, but may be helpful for others experiencing the same delema. Thanks in advance for whatever help is posted. Edited to add: I understand ITR is not using the GRI pump any longer, but don’t know the new supplier. These new pumps don’t need to be primed and run with water/glycol, in other words, they can be run dry without damaging the pump.

OK... Hello everyone. we are new to the forum and new to RV living, we are preparing to become full timers. so i am on an intense learning curve as we bought a 1999 Fleet wood Pace Arrow that needed minor work. so here is the problem that i am having right now. We have been staying in the MotorHome trying to become accustomed to staying here full time. i was going through the basement vacuuming everything I could reach with the shop vac two Saturdays ago. I had the basement lights on and i went working into the night as I also had a plumbing leak that I had to repair. To my horror the next morning i found that I had left all of the basement lights on. We had not yet been sleeping overnight in the Motorhome. The batteries were completely dead. i could not get the gen set to start but was able to start the motor and was able to eventually get a charge on the batteries by connecting a shoreline and was able to operate everything eventually. The problem started here... when I started the engine at idle the RPM's pulsed. This had never happened before and i have had the motorhome around two weeks at this point. it has been doing it ever since just not as bad. when they pulse at idle it is a steady up and down pulse. Another thing that has changed and I have noticed a difference in is that the lights have started to surge at times and I hear the converter under the refrigerator make surging noises. Today I drove the motor home around 100 miles and when i got back home to park and level I found that i could not get the hydraulic jacks to level the motor home. two would touch and then the hydraulic motor sounded like the motor would just loose power. This was with the engine running. I shut down the engine and connected shore power and turned the key on and the hydraulic levelers had full power and worked like a dream. Another issue that I found out was that the gen set would not power anything. I tried the generator before hooking up the shoreline because i thought that it might be a voltage issue. So now I am here in the motorhome and I notice that the lights are just not as bright as they normally are and i am just like " what in the world did i do to our motorhome". With all of that said I hope it makes sense what I am trying to convey. I am trying to get everything ready in the motorhome so I can move back to the west from the east. having a hard enough time getting rid of everything in the house let alone now having problems with my motorhome. I hope your knowledge and experience can help me in my predicament. I don't know if it is my batteries or the converter or both. Oh, just as a side note because it might be relevant. we had been getting a rotten egg smell in the motor home that was intermittent. and we were noticing a really strong smell at the front passenger side of the engine compartment as we would walk by it. I checked tonight and noticed that the chassis battery is located here.. could this be related as well. Thank you so much for your help and advise in advance. I'm trying to learn as much as I can as fast as I can and to be honest the electrical is seeming to be the hardest as it seems to be so foreign to residential electrical. BrownSquad
