To simplify what Chris just posted, which was great info.

If you don't have a volt meter get one, it will be the best tool for your RV.
  • Look at the pictograph that is circled in the middle, look for that on the bottom back of the charger for the same. This is the input from the solar panel. If it shows voltage above 12v (should be higher) it is getting good voltage and the wires from the panel are good.
  • If it shows anything less make sure that there are no obstructions over the panel, and it is in the sun. If anything was over it etc, clear and retest. If the voltage (late morning till around noonish) is not at least 12v you have a wire issue from the panel. There have been a few who have new trailers and their panels were never hooked up or the wired were barely connected.

If it is over 12v then also check the output (two wires just to the right in the pic) and see what those are showing. You could even unscrew those and see if they show the 12v from the battery. That would check the continuity from the battery back to the charger.

Hope this helps.. Troubleshooting these stink but as Chris said it will make you a more aware and better owner!

I think that, in terms of the controller, it should be as simple as looking at the front status lights and fault codes.
