Vibrator Motor
The vibrator uses a carbon brush-type electric motor. The
brushes in the vibrator motor are a replaceable item, and after
extended use, may need to be replaced.
NOTE: The position of the counterweights inside
the vibrator have been preset from the factory and
should not be changed.
Problem Diagnosis And Repair
Diagnosing electrical system problems involves identifying
the features, components, or functions which are not working
properly; then tracking and testing the system back from there.
A multimeter and two jumper wires (preferably with alligator
clips on the ends) will be needed for these tests. Most tests
will be checking for the presence of voltage. Make sure the
multimeter is set to
DC volts
(not amps or ohms) prior to
conducting these tests.
COMPLETE SYSTEM FAILURE
Should the whole system appear to be inactive, including
the vibrator and electric front door, when the vehicle’s engine
is running and supplying electrical and hydraulic power,
troubleshoot the electrical system using the following steps.
The vehicle’s transmission must be in the neutral position and
the parking brake set. All tests are to be performed with the
engine off so that there is no chance of accidental engagement
during the tests.
WARNING
Never perform any maintenance or troubleshooting
unless the vehicle’s engine is off and the parking
brake set.
1. Turn the master switch on the control box (if equipped)
to the ON position. The red light on the control box should
illuminate. If the red light illuminates, the electrical
problem is between the control box and the Turf Tender.
If the light does not illuminate, the problem is either with
the electrical system of the vehicle or in the wiring leading
to the control box.
2. Check the main power harness connector at the control
box making sure it is clean and making good contact.
Clean or replace as necessary.
3. Using a multimeter set in the 12 volts DC range, check
the voltage at the end of the main power wiring harness.
Being sure to observe polarity connect the red test lead
from the meter to the red (+) wire and the black test lead
to black.
Voltage greater than 11 volts
should be present.
Low voltage indicates a problem with either the vehicle’s
battery or the connections of the main power wiring
harness. If there is no evidence of damage to the power
wiring harness and the connections are good, connect the
main power wire harness to the control box.
NOTE: If there is a reading of zero volts, move the
negative lead from the power wire harness to a bare
spot on the chassis of the tractor which will give a
good chassis ground. Paint is a poor conductor of
electricity. If a voltage is present, there is a problem
with the ground (black) wire or it’s connection to
the battery. Check the connection. If the connection
is not the problem, replace the power wire harness.
4. Open the control box, and check the voltage between the
chassis ground screw (located on the inner left wall) and
the power lead (located on the fuse block). If no voltage
is detected, but voltage was present at the end of the
main power harness, the problem is in the power pigtail
of the control box. Repair or replace as necessary.
