fixed Pit flashlight

The LED flashlight from Scott (when we raced at Exhibition Grounds), which I had put into astronomy service with red film, had been acting up lately. Had another look. Ugh. All three AAA batteries had since leaked! Wow. Pried them out of the carrier and tossed them into the growing dead battery pile (sorry). Cleaned the carrier with vinegar. Cleaned the inside of the flashlight body too. Bad leak—paint came off. Did not see any activity at first but then the diodes flickered. Fiddled for a bit to determine the switch is wobbly. Corrosion on the contacts maybe? When I turned if off and on again (sorry) several times, it settled down. Back into astronomy box α (after removing the batteries).
