Brilliant, Hyflyer. I cut the top connection with a scalpel, then work hardened the two other connections and they snapped off cleanly after two to three waggles. Discarded the sensor and used a blob of solder, with a not so fine soldering iron, to connect A & C. Hey presto, our DC16 now works perfectly again, after two years sitting in the garage! Many thanks.
