Use this procedure during the installation of a
new variable frequency controller or during an
Apply the parking brake and place the propel control
lever in the STOP position. Stop the engine. Turn the
key start switch to the ON position. Put the throttle
switch in the HIGH position. Put the propel range switch
in the LOW position.
This procedure should be performed with the key
start switch in the ON position, but the engine
If necessary, tilt the platform in order to gain access to
the vibratory pump.
Disconnect the main wiring harness from the electrical
connectors for the vibratory pump. Assemble the
fabricated wiring harness. Refer to the illustration and
the charts that are provided for specific details. Install
the fabricated wiring harness in the main harness.
The amperage reading which is given during the
procedure may be used to predetermine the
vibration frequency values for the Variable
Frequency - Test.
In order to obtain the correct readings, the
nominal amperage values for the minimum
frequency settings should be checked and
adjusted before doing the maximum frequency
Connect the WV-7070 Digital Multimeter to item 2 on
the fabricated wiring harness so that the amperage
reading and the high amplitude solenoid may be
Select the correct am perage range on the multimeter.
The range of milliamperes which may be measured is
400 to 1200 mA.

Vibratory amplitude control.
Place the vibratory amplitude control (3) in the HIGH
counterclockwise position (minimum frequency).
Depress vibratory on/off control switch (2) in order to
supply current to the vibratory system.
The nominal amperage that is measured for high
amplitude-minimum frequency is 450 mA.
