Field experience shows that field flashing failures often stem from voltage drops in the relay coil power feed. During a recent maintenance outage at a gas plant, technicians traced intermittent K53A flashing relay failures back to a sagging 125 V DC station battery bank rather than a defective driver board. Always verify that your external J9 coil supply stays consistently above 100 V DC under load.
