See the MOTOR TEST PROCEDURE. The relays will engage and disengage (the clicking noise) when the
door switch is cycled if the motor is malfunctioning.
These general service notes and the following test procedures cover the most common problems associated
with Kwikee electric steps. Due to the number of variable conditions available, you may experience
symptoms other than those covered. Please feel free to contact the customer service department at 1-800-
736-9961 for further information or assistance.
TEST PROCEDURE - VEHICLE
WIRING:
Read the General Service Notes before
starting any test procedure.
1. Unplug the four way plug between the
control unit and the vehicle wiring. (See Figure
2)
2. TO CHECK THE MAIN POWER
SOURCE: Connect a voltmeter between the
RED wire from the vehicle half of the four way
plug and the ring terminal on the end of the 10
ga. green ground wire from the control unit to
the vehicle chassis (See Figure 3). NOTE -
Steps manufactured before August 26, 1991
used a braided ground cable to ground the step
to the vehicle chassis. The control unit on steps
manufactured after that date are grounded
directly to the vehicle chassis by the 10 ga.
green ground wire as shown in Figure 2. If the
step is equipped with a braided ground cable,
substitute the braided ground cable in place of
the green ground wire in these test procedures.
The reading should be about 12 volts DC. If
the voltage is low there may be a loose or
corroded connection, or low battery charge. If
the voltage reading is zero, check the 25 or 30
amp fuse/circuit breaker and all connections.
Be sure there is a good -round connection
between the step frame and the vehicle chassis.
See Step #2 of the HOOKUP PROCEDURE.
A good ground connection is a must. If the
reading is approximately 12 volts DC proceed
with the next test.
3. TO CHECK THE POWER SWITCH:
Connect the voltmeter between the WHITE
wire from the vehicle half of the four way plug
and the ring terminal on the green ground wire.
(See Figure 4) The reading should be about 12
volts DC with the power switch on and zero
when the switch is off. If the voltmeter reads
zero with the power switch on, the first item to
check is the inline fuse or circuit breaker in the wire between the power switch and the power lead (red
wire). If the fuse/circuit breaker is all right, connect the voltmeter between the terminals on the power
switch with the wire leading to the power wire (red wire) and the ground. (See Figure 5)
