Component Testing

For accurate resistance and/or continuity checks, elec-

trically disconnect the component being tested from the

circuit (e.g. unplug the wire harness connector from

component before checking continuity on the compon-

ent terminals).

CAUTION

When testing electrical components for continu-

ity with a multimeter (ohms setting), make sure

that power to the circuit has been disconnected.

E--Stop Button (Machines with Electronic Hydraulic Controls)

On ProPass machines with electronic hydraulic con-

trols, the E --stop button is used to disconnect battery

power to the machine. The E--stop button is a normally

closed switch that is located on the control panel guard

(Fig. 26).

The E--stop button is a two (2) position switch with two

(2)terminalsthatcanbetestedwithamultimeter.Make

sure that electrical power to the E--stop button is discon-

nected before testing the button. Disconnect E--stop

button connector from machine wire harness. Check the

continuity of the button by connecting a multimeter

(ohms setting) across the button harness connector ter-

minals. There should not be c ontinuity (infinite ohms)

between the connector terminals when the button is

pressed in. When the button is pulled out, there should

be continuity (zero ohms) between the connector ter-

minals.

If E--stop button testing determines that the button is

faulty, remove button from control panel guard and re-

place button assembly. Make sure that wire harness

connector is attached to the button after testing and/or

replacement.
