TEST OR INSPECTION
Ensure system air pressure is at least 85 psi (586 kPa) during this procedure. System air
pressure is required to activate valves.
Do not engage water pump engine during this procedure, except when performing
complete system checks. Valve operations can be checked without water pump
Valve operations can be checked by observing valve shaft rotation. Valves are open when
tabs or yellow paint tabs are aligned with fluid flow.
If system air pressure is below 85 psi (586 kPa), start engine and allow system air
pressure to build to at least 85 psi (586 kPa) (TM 9-2320-347-10). Then shut off
engine (TM 9-2320-347-10). Turn battery disconnect switch to ON position (WP 0007).
Put bumper turret control POWER switch to | (on) position (WP 0004). While an
assistant pushes bumper turret control discharge switch (WP 0004), check if bumper
turret valve operates to open position.
If bumper turret valve operates to open position, go to Step 15.
