Will FBH cut out if earthed?

macafee2 · 7th February 2019, 12:07

Without starting the engine and if the battery does not go flat and you don't run out of fuel, if you earth pin 3, it is pin 3 for my webasto, will the FBH ever cut out or does it keep running? Does it have its own temperature gauge?

If earthed, does it cut out and then restart when the coolant drops in temperature?

Yes Ian it will keep restarting once coolant temp reduces again. It goes into a standby mode under the conditions you describe. Lee.

So if i understand correctly,If say you were in Siberia you could leave the FBH on all the time to stop the car from freezing up with out a problem ? although not advisable.?

Yes but you would need more than 1 battery, a member who lives near to me left his running on and off over night and it drained his battery to 10v, but with an auxiliary power source you could do just that. Lee.

So it will start up regardless of the outside temp?

It will if you wire up a remote or a manual switch yes. Easy enough to do, I wired up my remote in under an hour.

sorry, a little knowledge is a dangerous thing.
I hope no one has tried pin 6.

Thank you trebor for correcting me
