Electrical System
4. If a proximity switch LED does not function correctly:
A. Disconnect sweeper power harness from tow ve-
hicle. Then, disconnect the proximity switch connec-
tor from the sweeper wire harness. Reconnect
sweeper power harness to tow vehicle.
B. Using a multimeter, verify that the sweeper wire
harness connector terminal for the appropriate wire
has 12 VDC when electrical power exists to sweeper
and sweeper is positioned as listed below.
Turn Around Position Switch (hole number 1):
Violet harness wire has 12 VDC when sweeper is
lowered and offset.
Transport Position Switch (number 3): Yellow
harness wire has 12 VDC when sweeper is low-
ered and not offset.
Offset Lockout Switch (number 5): Pink harness
wire has 12 VDC in any sweeper position.
Broom Enable Switch (number 7): Pink harness
wire has 12 VDC in any sweeper position.
Hitch Home Switch: Pink harness wire has 12
VDC in any sweeper position.
C. Make sure that gap between end of proximity
switch and frame sensing plate is from 0.110” to
0.170” (2.8 to 4.3 mm). If necessary, adjust proximity
switch (see Proximity Switches in the Adjustments
section).
D. Make sure that sweeper wire harness ground
wire (black) is closed to ground.
E. If harness wire has system voltage present and
gap is correct but switch LED did not function, re-
place proximity switch. Make sure that switch is
properly adjusted (see Proximity Switches in the Ad-
justments section).
5. After testing is complete, make sure that switch con-
nector is plugged into sweeper wire harness. Connect
sweeper power harness to tow vehicle.
