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
 
it will be a voltage drop, your power lead and earth have to be heavy cable with a short run back to the battery, if it starts with your engine running fine then I would double the cable size or run another length along side the existing one,
on mine I only have 2 feet of cable from battery to heater and don't have a problem,
 
I havent really any experience of these systems. But I do agree with Flyinghigh.

If I were to say 19/20 issues I have seen people have with Eberspechers the answer always seem to be a low voltage causing the issues. A re visit of the wiring as Flying high suggests i suspect is a good starting paoint from what i have gleaned

Any idea were the cable would be, on the heater, blower unit under the van or in wardrobe with all the controls, and water tank, this is on a Murvi, thanks for your help

Click to expand...

the control cables are quite light and control a relay that should be close to the main heater unit, likewise the heavy cable should go from the battery through a fuse then the relay, onto the heater itself, usually the main cable will be three times the thickness of the control cables, unfortunately I am not familiar with the Murvi wiring, but why don you ask Murvi your self? they may even furnish you with a wiring diagram and colour code to make tracing the feed easy,
