    Oh my how this helped me ! I just couldn't figure out why my sink GFI outlets wouldn't work and had no rest buttons. I search the fuse box, checked the breakers and was going to go under the sink when I found this video. It explained it all clearly. My bathroom GFI reset button works for the kitchen also. All connected. Thank you!

    I have a 2007 Keystone Outback M 23RS model plugged into wall outlet using heavy duty RV extension cord but still has no power to run AC ( Carrier RV) and Fridge (Dometic autoref temperature controlled) after it shut off from low power to shut off entirely yesterday; checked GFCI and Circuit breakers which was initially changed to the proper rating and amperage due to 3 blown fuses upon checking after the power shut off (2 40amp fuse and 1 20 amp fuse); the alert meter propane gas detector was blinking red to steady and now not on green but dead. I was informed as well that 2 30lb propane gas was low initially as it has been used, All RV outlets working including lights, excluding Stereo(Jensen) which s not working, no power on, but Microwave is on as tested. Need help to turn on AC or Fridge so as not to overload. Please and thank you

  • @alma-pw2em
    @alma-pw2em ปีที่แล้ว

    Please help! I have bought two batteries now both deep cycle batteries 12 volt 690 MCA 101 amp hours. Both of which have died on me. I live in the rv full time so I'm guessing it relies a lot on the battery. The rv is also connected to a 30 amp breaker switch inside of my parents house. This is in a 2004 Keystone Outback 28 RLS and I can't find anything online about it. Do I need a bigger size battery or what is my problem?

  • @evenstargalaxy9586
    @evenstargalaxy9586 2 ปีที่แล้ว

    We have a Passport Elite 19RB. When plugged in to 30 amp service, we can use the outlets to power appliances. When we are not plugged in, is there an inverter that changes the 12v to 120 to power appliances like a CPAP? I guess my question is, is there a built in inverter that services the outlets by the bed, in the kitchen or in the bath, and behind the TV?

    • @KeystoneRVCompany
      @KeystoneRVCompany  2 ปีที่แล้ว

      Good morning, this is a great question. Because this is a VIN specific question, you'll need to call with your VIN and speak to our call center to confirm what your unit came with or is prepped with. The number is 1-866-425-4369 and they are open Monday - Friday. We will note, if you have inverted outlets, then the outlets themselves would be marked to identify which ones are inverted. Thank you.

    After a very frustrating day of checking power, breakers, fuses, searching websites and watching videos (like this one) attempting to learn why the air conditioner in my 2020 Keystone Hideout wasn’t working I found a service technician who told me about the (unlabeled) switch above the fireplace that disables the AC.

  • @boggynfld

    Why does the battery/12V system use black and white wiring? This is too easily confused with 120Vac hot and neutral wiring! Also, why would the black 12V wire be positive? On cars/trucks, black is negative. I don't understand why the 12V system doesn't use the same color code as cars and trucks.

    If you use a 30 amp adapter on a 50 amp receptacle you are saying that its only good enough to run the battery charger and nothing else? Would you not be able to use 30 amps?

    • @KeystoneRVCompany
      @KeystoneRVCompany  4 ปีที่แล้ว +2

      Unfortunately, the unit cannot “step up ” in amps. You can only use an adapter to “step down” from 50amp to lower amperages.
      You cannot go from a 30amp and plug in to a higher amped plug, even with an adapter you cannot adapt up, only down.

    I have a 2022 Passport GT Series with 2 solar Panels and 2 batteries. We're at an RV park and went through a storm. Since we didn't yet have our Surge protector, we unplugged from the 50Amp outlet and figured that the 2 Solar Panels and 2 batteries would be enough. Except that the TV shut off, lights dimmed. The Panel with battery level was blinking & beeping that it was low. We plugged back in and I reset the GFCI which brought back the TV. My question is, with 2 solar Panels and 2 batteries, why did I run out of power? Am I supposed to flip some kind of switch to tap into the Solar energy? The Battery Disconnect was on.

    • @KeystoneRVCompany
      @KeystoneRVCompany  2 ปีที่แล้ว

      Good morning, we are sorry to hear you’ve had issues with your unit’s solar system. There isn’t enough information provided here for us to be certain what is happening. Based on what you are noting, as long as there was sufficient sun, and stored energy, the batteries should be charged up even with the 200 system. There may be an issue somewhere in the line, however, we can’t be certain until you’ve confirmed the following and have this formally inspected. You’d want to see the status of the Victron App to see what power is coming in/going out, and we’d want to see that the batteries are testing good. If the controller and batteries are good, there should be enough power to keep the lights on. The TV wouldn’t work unless you purchased an aftermarket inverter for the inverted outlets. Not sure if you did that, as you don’t mention that here. The batteries and inverter are not included by Keystone RV. I would ask that maybe you report your findings and any further questions through our retail team at 1-866-425-4369 Monday - Friday with your VIN. We do have solar experts in our call center that can also answer questions and troubleshoot with you. Thank you.

    • @KeystoneRVCompany
      @KeystoneRVCompany  3 ปีที่แล้ว

      Good morning! If your awning and lights are not working, we recommend to check the voltage on your RV battery. You would need between 12.6-12.8 volts in order to run the components properly. If you need further assistance with this or you have any other questions, please reach out to our Owner Relations Department at 1-866-425-4369. Thank you!

      That is a great question. The converter fan will run at all times when you are plugged in to a 110 power source or shore power. We hope this helps answer this for you. Sounds like it should be operating as designed.

    @asuarezjd 2 ปีที่แล้ว

    I bought a 219BH Passport and it is solar ready. I bought an expansion panel and is fine, but then when I was going to install the inverter...I removed the "future inverter location" box and a 20AMP yellow Romex wire appeared, no ends, is a loop so it comes out of the wall and goes back inside the wall. I don't see any other wires (to the battery) but the converter is next to it so I guess I can wire it directly to the LOAD connectors in the converter. How do I find pictures or instructions on how to deal with the ROMEX loop? I was expecting a terminal or end of the cable. The owners manual reads that is "pre-wired for seven outlets" but I pull and both ends seem to be connected unless it is snagged and I am too weak or afraid to pull hard.
    My thing is that if it comes prewired is best to use it and looks like that Romex protruding out of that hole like an intestine is where it needs to go but it does not make sense to splice it. I called and chat with Keystone but the girl in the chat had no idea and when I asked for a diagram, like the blue prints of a house, she said they don't send those to customers. Not even the roof plan to see where the joists would be for the solar panel brackets. I could test the wire but I don't want to cut the insulation. I took pictures but I don't know how to upload them here, I could send them in an email. My thing is that I understand the concept and I have done a lot of electric since my father was an electrician and I his helper until I was 21, but I don't know if the Romex comes or goes to the panel, converter, or just directly to outlets (which I doubt0 and why is it a loop and not an "end/tip".

      Good afternoon, we will do our best to get you an answer here shortly on this! Thank you for your inquiry, and we'll respond here soon. Also, if we need photos we'll direct you to sent them to ownerrelations@keystonerv.com directly. However, I would wait until we get some answers on this first. Thank you.

    • @KeystoneRVCompany
      @KeystoneRVCompany  2 ปีที่แล้ว +1

      Good morning! We do appreciate your inquiry. There are several things to keep in mind and so we will give you the best feedback we can based on the information you provided in your comment. Yes, the wiring is looped and we do NOT recommend pulling on it. It’s a simple receptacle circuit, which we do not label or have any schematic to provide to help you in your efforts with that. For safety reasons, we do not recommend RV owners to work on their 120V system. We do not have a video for the installation of the inverter for this reason as well. What we can do is refer you to a local authorized dealership for assistance with installation of the inverter itself. www.keystonerv.com/find-a-dealer. They will be able to guarantee their work, and you’ll have the peace of mind knowing it was completed by an authorized location. We also have a team here on the dealership service side for support if needed. What we can advise regarding mounting of the solar panels is that the roof is 3/8” decking, and the panel can be installed pretty much anywhere on the roof where there is room as long as your cables near the port, typically within 3’. We hope this information helps you in your efforts. Thank you!

    If we remain on shore power and the converter is converting AC to DC, why is a battery necessary?

    • @KeystoneRVCompany
      @KeystoneRVCompany  2 ปีที่แล้ว

      There are directly related 12V items supplied to the unit that do not come from the shore power. Such as your slides and jacks. There are many features in the RV that require a 12V battery source in order to operate due to how the unit is wired. If you have additional questions about this, please feel free to reach out to our retail team directly at 1-866-425-4369. Thank you.

    I disagree-this is an excellent video. If you were confused you need to watch it a few times. You should understand this stuff before you camp/

    Is there a fuse for the battery charger? If the charger is not working do I have to replace the entire DC convert?

      Good afternoon, yes, there are 2 (40AMP) reverse polarity fuses on the converter itself. The output of the converter should be 13.65 volts when plugged in to shore power. The converter will not charge the batteries when not connected to shore power. If the converter has lower than 13.65 volts in output, you'd want to contact a dealership or service center. If the unit is 2 years old or less it may still be covered under warranty. If it is older than that, they'll at least be able to assist you in ordering a replacement.
