210 series leveling jacks joystick

X2 on what Doug said. Great answer. What rig is this on? Also are they "stuck" up or down?

Usually, when a 100 or 200 system pump fails to activate, the solenoid on the Pump is defective. All the Joystick does is send a Ground signal to the solenoid. To check the pump, you jump across the 2 large terminals on the solenoid with a large screwdriver. If the pump runs the motor is GOOD. You then look at the 2 small wires on the solenoid. Test for 12 volt positive. Once that terminal is located. jump a ground wire to the other terminal. If the pump does not run , then the solenoid is bad. If it does run, then the ground wire from the Joystick is open somewhere(very rare). Doug

Pump locations vary by manufacturer, model and installer if after market.
You should put your rig in profile.
What is make and model of your rig?
My pump is located in front of the left front tire.
There should be a healthy sized wire coming directly off the battery that feeds the pump. Somewhere around a #2.
It should have a fuse or circuit breaker along the way.
Suggest locating battery and then trace out the large positive wires.
