Wiring schematic please? From alligator battery clipped end to the electric control junction box. Then from the control junction box to the deadman switch. I went to hook up the two black wires in the control junction box and it opens the aqua valve with the deadman switch not activated

Page 7: How Mbm Systems Works
When the control handle is released in a pressure release system, the reverse effect takes place in the blast system. The Auto Air Valve closes stopping the air flow and the dump valve opens causing a quick release of compressed air. Copyright© 2015 Mod-U-Blast®, All Rights Reserved...
Page 8 (MBM Blast Pots with T-Valves) the pressure vessel remains filled with compressed air. The compressed air remaining in the pres- sure vessel is released when the inlet valve is manually closed and the blow-down valve is manually opened. Copyright© 2015 Mod-U-Blast®, All Rights Reserved...
Page 9 (MBM Blast Pots with combo valves) the combination valve automatically closes stopping the flow of compressed air and releasing the Blow-down Hose. The compressed air remaining in the pressure vessel is released through the Blow- down Hose and blasting ends. Copyright© 2015 Mod-U-Blast®, All Rights Reserved...
