EAS manual overide

Hi,
Continuing on from a previous topic re EAS a couple of questions if anyone has had the experience :

1. rangerover.net suggests turning on the ignition to run the compressor ( bridging two pins on the disconnected ECU connector of the EAS) - what would happen if the engine was running?
2. Pin 13 of the connector should read a voltage rising to 12v ( correct pressure achieved ) - but I get none at all ?

Its been a long time since I did it but I thougt it just went from 0 straight to ~12. I think it's a simple switch not a thermistor type.

Cheers spud - did you ever run the engine at the same time to reduce battery drain while compressor was "jumped" ?

Sorry - just saw your earlier reply spud
