Found your 12 volt power is out and you have an Odyssey system? Odyssey screen not powering up and blank? Most of the time, it's relatively simple to get the lights running and the fridge cold again. Several things can shut the 12v power down. By following the steps below to check each likely cause one by one, you'll maximise your chances of finding the cause of your problem.
Check the Battery Voltage.
The battery level indicator is shown clearly in orange on the left of the Odyssey screen. By swiping up from the bottom of the screen, you can bring up the voltage level, which will be on the left of the slide up section.
Check your Load Isolation Switch.
The Odyssey system has two modes of load isolation. One is on the Odyssey Screen, and one is with the BatteryPlus35, in your electrical cupboard.
On the Odyssey screen, the button labelled "Eco mode" will turn off the main 12v power. Pressing this will cycle the main 12v power on and off.
Make sure you try this on your phone app as well, in case the problem lies in the screen. Be sure to check “How do I use my phone to control my Odyssey system?”.
Master Isolation Switch
This will be a black switch near the BatteryPlus35. It is designed for long term storage where it is not possible to charge your RV for extended periods (2-4 weeks, it should never bed left longer than this without checking). If this is off, the Odyssey screen will not receive charge and will shut down, eventually going completely flat. If this happens, the tablet may need to be recharged. This can take up to half an hour to turn on after cycling the master switch.
Check the main fuses.
All battery management systems will have a fuse, rated between 30 and 40 amps, on the positive output side of the batteries. If this has blown or shaken loose, it is likely the cause of the problem.
Remove the fuse, holding it up to the light and check to see if there are any breaks or marks in the internal metal.
Even if it doesn't appear to be faulty, it's not a terrible idea to try another fuse. It's always a good idea to check the size of the fuses you have and buy spares to suit.
Still no luck?
If after these checks you have not found the cause, take note of the voltage (if possible) and the status lights of your battery management system, paying particular attention to the colour, quantity and frequency of the flashes displayed. The status lights are on the bottom right of the BatteryPlus35 range. If there are any error messages displayed on your Odyssey, make a note of these as well.
