Rotolight repair

June 25th, 2008

Trög has really nice Pinttsch Bamag rotolights on the top.    These lights feature 3 aspheric glass lenses which rotate around the central light.     This yeilds a nice flash pattern, better than the rotating reflector design of most other lights.

The left light rotates fine, but was failing to shine.   What I thought was going to be a simple change of bulb ended up being a several hour repair.   It turns out the ground connection at the bottom was a pieces of galvanized steel crimped against a galvanized nut.   Over time, the crimp loosened and corrosion degraded this connection.    The “fix” was to weld the crimp to the nut.   Easier than disassembling further and cleaning everything up, especially since it’d soon corrode again.

Oh, and another Tollarp rant.   What goofball thought it a good idea to make the ground wire red and the power wire black???!??!?
