Another cooling fan question
We have an original D180 RV12. Today, after a one hour flight in warm (by UK standards) flight at 13 degrees C at 4000 feet we landed, switched everything off and the fans and fuel pump kept running! Eventually we pulled the fuse, and went for lunch. On re-inserting the fuse an hour or so later all was quiet, so we flew back to our base with no further problem.
How could the fans/pump run with the master switch off?
