Question:
I have a fso6b1 fogatti water heater that is not getting power to the blue thermostat wires inside the control panel The unit has power directly to a battery and I wire tested it amd it lights up however when I test for power at the blue thermostat wires there is no power

Since you have power to the wire you're connecting to the Fogatti RV Tankless Water Heater # LSB64FR, but the water heater itself doesn't have power, I recommend checking to make sure it is wired correctly.
The 2 blue wires coming out the back of the unit will run to the thermostat while the red should be connected to 12V power and the black to a ground. Make sure this is how you're connecting the wires and that they are secured properly when you make the connections.
Let me know if you're still having issues and I can help you look into this further.
