Esterline Angus L1102S Chart Recorder

The Esterline Angus L1102S Chart Recorder is an analog data‑acquisition device that uses a rotating drum and pen to plot electrical signals over time. Common failure points for this vintage model include worn or broken pen bearings, degraded magnetic tape or chart paper feed mechanisms, corroded contact pins on the drive motor, and failing power supply capacitors that cause erratic drum speed or signal loss. First‑check diagnostics: verify 12 V/24 V DC input voltage and ripple; inspect the pen assembly for wear or obstruction; examine the motor windings with a multimeter for continuity and resistance; review any stored error codes or audible fault tones from the control board.[oss-gpt-20b]
