Aircraft X set out with Anti-Skid Control box along with Stores Parts Compatibility List and Maintenance Manual. Installed box to see if problem would be fixed; followed Maintenance Manual for trouble shooting with no help. Moved Aircraft X to [Ramp] pad and went back to Shop to gather more information and talk about what we wanted to do next. [I] talked about installing everything back to original. Troubleshoot for eight hours; found two problems; fixed them but failed to double check with my Partner that the original [Anti-Skid Control] box was back in Aircraft X and failed to document Anti-Skid was installed for troubleshooting. Also did not verify Serial Number on [Parts] Tag for new Anti-Skid box. [Recommend] verifying that the original box is in the aircraft [and] make sure to document the removal of component for the aircraft.
A Line Mechanic failed to properly document on a Non-Routine write-up that he had removed an Anti-Skid Control box and installed a new box in an aircraft for troubleshooting purposes. The new box was not removed due to a lack of adequate communication between himself and another Mechanic.
