Poor contact in the connector terminals. Defective power supply PCB. Defective engine PCB.


Reinsert the connector. Also check for continuity within the connector cable. If none, remedy or replace the cable. Check if the zero-crossing signal is output from YC2-5 on the power supply PCB. If not, replace the power supply PCB. Replace the engine PCB if C6400 is detected while YC2-5 on the power supply PCB outputs the zero-crossing signal.
