Adiebt Posted September 2, 2018 Share Posted September 2, 2018 With hook up charging both leisure battery and starter battery run the cab aircon with the ignition in the first position to cool down the van whilst pitched up ? Just a hypothetical question . Cheers . Link to comment Share on other sites More sharing options...
colin Posted September 2, 2018 Share Posted September 2, 2018 The aircon runs directly off the engine, all you could do is run the fan. Link to comment Share on other sites More sharing options...
aandncaravan Posted September 2, 2018 Share Posted September 2, 2018 Regardless of what would work, there is another issue of replacing the current drawn. Most good Habitation battery chargers only give limited charging to the Starter battery. Most of the time the habitation battery is likely to be low, the Starter battery is likely to be full, so will only want a small charge, so the best chargers drop the voltage and limit the current. It is therefore possible that, over a period, the fan would draw more than was being put back and the Starter battery would discharge. Link to comment Share on other sites More sharing options...
