the ignition is on and zero when the ignition is off. If the reading is zero when the ignition is on,
check the connection of the yellow wire at the vehicle's fuse panel. If connected at a fuse, check
for a blown fuse.
NOTE - On some installations there may be an inline fuse or circuit
breaker in the YELLOW wire that should be checked Kwikee Products Company, Inc.
recommends that this
fuse circuit breaker be installed at this time if the Yellow wire is not
already fused . If the reading was about 12 volts DC when the ignition was off, the YELLOW
wire is connected to a constant live source. On control units #9513 and #9590, if the YELLOW
wire is connected to a constant live source, the step will always activate with the door movement,
even if the power switch and ignition are off.
NOTE - On some travel trailer and fifth wheel applications, the ignition safety system may
not be connected and the voltmeter reading will be zero between the YELLOW wire and
the ground wire.
TEST PROCEDURE - MOTOR TEST:
6 . When checking the motor, remove the two (2) screws from the connector on the motor leads
between the motor and control unit. Separate the seal assembly exposing the connectors on the
red and yellow motor wires.
CAUTION : Make note of how the wires and connectors assembled
for reassembly later. The wire connectors may be led wrong even though the colors match
Disconnect the motor leads.
WARNING: Under no condition should power be applied to the motor leads while the
motor is still connected to the control unit or damage to the control unit will result voiding
the warranty.
Connect a 10 gauge jumper wire to the RED wire in the vehicle half of the four
way plug. This wire must have power. See Step #2 of the VEHICLE WIRING TEST
PROCEDURE: Connect another 10 gauge wire to the ring terminal on the end of the 31" long 10
ga. green ground wire (See Figure 8).
TO RETRACT STEP: Connect the ground jumper wire (Jumper from the green ground wire) to
the RED motor lead. Touch the power jumper wire (Jumper from four way plug) to the
YELLOW motor lead.
TO EXTEND STEP: Connect the ground jumper wire (Jumper from the green ground wire) to
the YELLOW motor lead. Touch the power jumper wire (Jumper from four way plug) to the
RED motor lead.
CAUTION: Do not leave the jumper wire connected to the motor for more than it takes to
extend or retract the step or damage to the motor may result.
If the motor fails to move, the motor may be defective. If the step has been struck by some kind
of road hazard, the step mechanism may be bent and causing the step to bind. The control unit
would then shut off power to the step as described in the BASIC SUMMARY OF OPERATION.
Check for physical damage to the tread, sliding rails, extending arms, etc. Also check all pivot
points for rusting. (See the LUBRICATION AND MAINTENANCE SCHEDULE)
If the step doesn't move when power is applied to the motor terminals, but a dim spark is
noticeable, there may be damage to the windings inside the motor, requiring replacement of the
motor. A dim spark may also indicate a shorted or burned out motor requiring replacement.
