Service Bulletin/Repair Instructions
Altec has learned that the single-axis joystick controls on certain AH model units built from December 2020 to February 2025 could experience nuisance system error lights and parameter faults. This could lead to reduced functionality of interlocks. These joysticks are at the upper controls on AH75B/85B/100B units and at both the Upper and Ground controls on AH125A-S units.
