Re: Onan/Cummings Generator drains the batteries
Thank you all so much for your suggestions. This is our first RV and we are having trouble identifying locations of some of the parts you have suggested we check. I have tried to research diagrams or manuals that identify them in our specific model, but have not had any luck. We have tried some of the suggestions by other heartland owners as to the location of various components, but find that ours is apparently not the same. We tried to remove the wall in the "basement" as some have suggested, but ours has many items attached on the back side and it appears that it cannot be removed, so we feel stumped. Does anyone know where we can find specific diagrams for the RW 305? I called Heartland when new, and they said they dont produce them, but check the owners forum.
The RW305 is the same model as the Cyclone 3010, which we have, so as long as things haven't changed too much - here goes.
Standing on the door side looking in the basement. looking to the left (towards the rear) you should see a "pie plate", about 4-5" in diameter. This is an access plate that unscrews. Removing the center cap should give you access to the convertor 110 AC plug. Above the pie plate and nearby there should be a louvered vent.
Find those two items you you will now know where the convertor is located behind the wall.
Your rear wall may be in 3 sections. Wide piece in the center, 2/3 size of the center angled piece on the ODS (off door side) And a shorter section that is on the door side.
There should be 4 screws attaching the center wall and 4 screws attaching the angled ODS wall. But, that wall may have 2 screws along the inner vertical edge and 2 screws going perpendicular to the wall coming from the UDC (universal docking center)
There should not be anything attached to the wall from the factory preventing it from being taken down. If you have the yellow eureka central vac that protrudes though the wall, be advised it is not attached to it, only supported by it. Remove the cap and slide the wall off the vacuum.
The transfer switch you read so much about here is behind that center wall panel. The clunk it does when activating is a sign that it most likely is working.
But, before removing the walls - If you can hear the converter humming, odds are it is working.
Check those circuit breakers, the 110 AC breakers on the genny and in main panel
The 12 volt breakers in the front bay along the wall.
If they are all good and everything else seems to work in the trailer, check the fuses in the fuse panel next to the main AC circuit breaker panel.
Lastly, there are fuses on the converter itself, which you may need to remove that wall to get to.
You might be able to check - get to them by removing the louvered vent.
To get that section of wall down you have to remove the trim that goes across the opening of the basement and screws to the floor rafters of the bedroom. The trim, about 8's wide and covered with black carpet covers the chase where many wires are run.
