Yes, that's another issue. I think a new glow plug should fix that though.

Thanks for input. I think the largest possible battery is the easiest (but not the best) solution for using the aux heater with engine off. So basically I need to override the outside air temp sensor, the 'engine on' sensor which are both on the eberspacher. Then I either need to have the ignition on to run the aux water pump or have that pump switched on independently. Could be don't with one switch maybe. Just need a wiring diagram! Some of the wires are under the wipers, I understand.

Aaah, brilliant. What about with the engine off? Does the auxillary water pump come on as well? Thanks

Hi Folks, Has anyone fitted a DIY override switch for the aux heater? Or bought a low cost kit, possibly with a timer. I'd be very interested to hear from anyone who has done this. The wiring diagram on the Mirez web page http://www.mirez.co....Information.pdf shows that you would only need a double pole switch to give 12v to the temp sensor and engine on sensor inputs. Would this be all that's needed? Would the electric water circulation pump also come on automatically? Any thoughts? Cheers
