Wisi Antenna Relay BEFORE                                                                 Same Relay AFTER restoration
It appears hard to believe that these are the same relay. The multiple telescoping  sections of automotive antennas are NOT watertight. As moisture is squeezed through the intersecting sections, especially when retracting the antenna mast during a rain, water is able to enter the motor mechanism and cause nasty corrosion. This WISI remote antenna relay bathed in rain water for several years in its captive gear housing.  I was able to restore the entire antenna fitting a rare 1955 Mercedes 300 SL.
The armature was RE-Wound                        
All parts cleaned and restored
