The Daco B91652‑A4 is a precision machining control board used in CNC and automotive assembly equipment. Common failure points for this class of boards include burned or cracked power input capacitors, degraded MOSFETs on the motor driver stage, and solder joint failures at the high‑current I/O pins. First‑check diagnostics should verify the 24 V/48 V supply rails with a multimeter, inspect the board for visible burn marks or loose connectors, and review any logged error codes from the host controller.[oss-gpt-20b] |
