Brush and Hopper Down Relays
The electrical system of the Pro Sweep 5200 includes
two relays: the brush relay and the hopper down relay.
These relays are identical and are located in the control
box enclosure.
The brush relay is used to de–energize the brush motor
solenoid (S3) when the hopper up/down switch is
pushed to raise. When the brush relay is not energized,
brush motor operation is possible.
The energized hopper down relay allows current to the
brush switch when the hopper down switch is closed
(hopper lowered). If the hopper is raised, the hopper
down relay will not be energized to prevent brush opera-
tion.

NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually

0.5
ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.
1.
with a multimeter (ohms setting). Resistance should be
from 70 to 90 ohms.
Verify coil resistance between terminals 85 and 86
2.
Connect multimeter (ohms setting) leads to relay ter-
minals 30 and 87. Ground terminal 86 and apply +12
VDC to terminal 85. The relay should make and break
continuity between terminals 30 and 87 as +12 VDC is
applied and removed from terminal 85.
3.
Disconnect voltage from terminal 85 and multimeter
lead from terminal 87.
4.
Connect multimeter (ohms setting) leads to relay ter-
minals 30 and 87A. Apply +12 VDC to terminal 85. The
relay should break and make continuity between termi-
nals 30 and 87A as +12 VDC is applied and removed
from terminal 85.
5.
Disconnect voltage and multimeter leads from the
relay terminals.
