Caterpillar 980F Cluster Gauge Assembly is the central electronic control board that drives the hydraulic gauges, speedometer, and other instrument displays on the 980F wheel loader. Common failure modes include loss of display output due to a failed LCD driver IC or broken trace, intermittent power cycling from a bad main power connector, and corrosion‑induced shorting in the gauge wiring harness. For this class of industrial control boards, also watch for overheating of the voltage regulator and degraded signal integrity on the CAN/LIN bus lines. First‑check steps: verify 12 V supply to the board with a multimeter, inspect all connectors and solder joints for corrosion or cracked traces, and read any stored fault codes from the loader’s diagnostic port before proceeding to component replacement.[oss-gpt-20b]
