ignition fails to engage inner warning lights flashing

Just got my truck out of shop clutch replacement with s South Bend G56 Clutch system.

Went out to trunk to drive to vehicle inspection. Put key in ignition and got nothing. Did a load test on batteries they were drained. Hooked a charger and tried again and got warning lights, interior dome lights and gauges all flashing away non stop even with key removed. For the time being I have disconnected the ground. This truck has never been a problem to start or run even when the clutch had a complete failure
