14.To check the power switch, connect the voltmeter between the white wire from the four-way plug
(vehicle half) and the terminal at the end of the control unit's 10-gauge green ground wire (see Figure 8).
The reading should be a minimum of 12 volts DC (The same as in Step 13) when the switch is on, and zero
(0) volts when the switch is off.
If the voltmeter reads zero (0) volts when the power switch is on, there is
a problem in the power switch circuit.
Check the 5-amp in-line fuse, the Power Switch itself and the condition
of the circuit s wiring and terminal connections.
15. To check the door switch, connect the voltmeter between the red wire
from the four-way plug (vehicle half) and the brown wire in the same
plug (see Figure 9). The voltage should be about 12 volts DC (the same
as in step 13) when the door is open and zero (0) when the door is
closed.
If the readings vary (either zero (0) volts when the door is opened or 12
volts continuously) there is a problem in the door switch. Check the door
switch and the condition of the circuit's wiring and terminal connections.
16. To check the ignition override system, connect the voltmeter between
the yellow wire from the four- way plug (vehicle half) and the ground
terminal on the end of the control unit's 10 gauge green ground wire (see
Figure 10). The voltage reading should be approximately 12 volts DC
when the ignition is on and zero (0) volts when the ignition is off.
the reading is zero when the ignition is on, check
his concludes the Step Test Procedure. At this point,
If
the terminal connections in the vehicle's fuse/circuit
breaker and the condition of the circuit's wiring and
terminal connections.
NOTE -The step wiring
circuit must be independent. No other device (i.e.
alarm systems, step well lights, etc.) can be
connected to the step wiring circuit. Any device
connected to the steps wiring can cause the step to
malfunction and will void the warranty.
T
the source of a steps malfunction should be known. If
