15 Using the jumper wire, jump from relay K12,
terminal 87A to terminal D4 below the blue
wire.
Result: The left steer end oscillate cylinder will
extend causing the machine to tilt away from
you. This simulates closing the right rear limit
switch causing the left oscillate cylinder to
extend.
Result: No movement. Verify there is voltage
on the jumper wire. Check for voltage on relay
K12, terminal 30.
Oscillate operates in the incorrect direction.
Do not proceed. Contact Genie Product
Support.
Note: Remove the jumper wire from relay K12 and
terminal D4 after the limit switch activates the
oscillate in the opposite direction.
16 Using a volt meter, check for voltage by
connecting the positive lead to relay K12,
terminal 87 and connecting the negative lead
to the ground strip terminal.
Result: The volt meter should read 0V DC.
Result: The volt meter reads 12V DC or
greater. Check terminal 86 for voltage. If yes,
the drive controller is activated or the ECU
needs to be replaced.
17 Move the drive controller just of center in a
safe driving direction.
Result: The volt meter should read 12V DC or
greater.
Result: The volt meter reads 0V DC. Do not
proceed. Contact Genie Product Support for
assistance.
