- Page 23 TroUbLEshooTiNg Line Fault: If the DUAL48M says “Line Fault” when no stations are running, the most likely cause is a direct short between the two wires in the two wire path (red and blue). If the Line Fault message only appears when a station is turned on, the problem is most likely a short in the decoder-to-solenoid wiring for the affected stations.
