Component Testing
For accurate resistance and/or continuity checks, elec-
trically disconnect the component being tested from the
circuit (e.g. disconnect the switch connectors before do-
ing a continuity check on switch).
CAUTION
When testing electrical components for continu-
ity with a multimeter (ohms setting), make sure
that power to the circuit has been disconnected.
Control Handle Switch
The control handle switch is used to activate the Top-
dresser 2500 brush and conveyor by energizing sole-
noid valve coil (S1) on the hydraulic manifold. When the
control handle switch is in the OFF position, the solenoid
is not energized, allowing hydraulic flow to bypass the
brush and conveyor motors.

On machines with serial numbers below 250000000,
the control handle switch is a toggle switch (Fig. 3). On
machines with serial numbers above 250000000, the
control handle switch is a rocker switch (Fig. 4). The
function of either switch type is identical.
