Narrative:
On aug/xa/00, I assisted another mechanic on deactivation of autospoilers per MEL 27-08C. A miscom may have occurred, after the procedure was fully accomplished, resulting in circuit breakers X30 and P33 being pulled and collared. Maintenance control assures me that the system has been re-evaluated, and is currently ok per the MEL requirements.
