I have a very sensitive clip on current ammeter and I went around my Classic Plus 8 checking a few residual drains and decided it was easier to throw the Red switch every time. I have left her for 8 weeks once on a holiday and she fired up straight away, the ECU soon relearns the temporary information so it makes no difference and out of interest the radio is the only remaining drain once the Red switch is thrown so I don't loose the memory on the Becker unit - this may not be the case with the Aero 8.
