Bobcat 66778674 Skidsteer

Bobcat 66778674 is a skid‑steer loader equipped with an electronic control board, hydraulic pump, and motor drive system typical of Bobcat’s T66/T70 series. Common failure points include the main controller board (overheating or shorted ICs), power supply modules (voltage regulator failures), and hydraulic pump solenoids (seal wear or leakage). For initial troubleshooting, verify that the battery and alternator are delivering correct voltage to the control unit, inspect all wiring harnesses for corrosion or broken connections, and review any stored fault codes on the display panel before proceeding with component replacement.[oss-gpt-20b] Post Comment
