Component Testing; E--Stop Button (Machines With Electronic Hydraulic Controls) - Toro ProPass 200 Service Manual

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).
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. 16).
The E--stop button is a two (2) position switch with two
(2) terminals that can be tested with a multimeter. 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 continuity (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.
Electrical System
When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
