Press the battery on the cables surrounding the solenoid valve, and then use the torch or lamp to prove that there is enough energy.The lamp should be activated, as with the multimeter, and if the valve is working, then it should also be opened.Press the battery onto the wires, and then use a torch or lamp bulb to see if there is enough power going through. The valve should open if it is working and the bulb should light up.
