Take apart switch

Take off the wiring form the lockout switch.

Take wrench and loosen the screws and take out the switch from the adaptor.

Take out the adapter from the servo control valve assy.

Switch ID

Take the switch from the adaptor.

Put a test light on the switch terminals. If you use a multimeter put it on the ohms. If the light is on, it means zero ohms and if your light is off it means infinite ohms.

The ball at the end of the switch is not pushed in, when light is off, but when you have it pushed in, then it is a normal open switch. And when that statement is in reverse it is normal closed switch.

And try not to push in the ball where it is even with the housing, you could damage the switch.

Make sure you disconnect your battery on equipment when doing test, may shock you, make sure parking brakes are on or having the equipment moving at all. It could harm you while running these test.

Also, hydraulic fluid could possibly leak out of servo control valve while taking out the lockout switch and adaptor. Make sure to turn off the reservoir to the pump and drain it so the level is below the servo control valve.
