This video shows the behaviour. It cuts out at 1m20s and 2m20s into the video. Not that the voltage doesnt drop noticably before the cutout. Then I notice something funny, it still shows voltage at the battery terminals after key is turned off. Must be voltage coming back from capacitors in the controller??? Or key mechanism problem?
