Has anyone got a fix for the below
No electric hook up, start heater up it goes through all its cycles fires up and then after a minute or so before it blows out the vents shuts down, this is on hot water or heating. I have fitted 2 new 110 amp leisure batteries, they are fully charged, having just come off mains at home, driven for 1 hour, and then the solar panel is also topping up.
If I start the engine up it all works fine, then turn engine off still works fine, its that initial start up, have tried switching from hab battery and engine battery, if on mains always works fine

Check that all of the battery connections are clean and tight. A connection with corrosion on it will be high resistance. It sounds as if you are trying to operate the eber with low voltage (when engine not running and not on hookup) and ebers do not like that. To start up an eber can take a current of 25 amps. HTH.
