If the reading is still zero check the wire
leading to the power lead for a loose
connection or cut wire. If the reading is about
12 volts DC, turn on the power switch and
check the other power switch terminal in the
same manner, by connecting the voltmeter
between the terminal and ground. If the
reading is zero, replace the power switch. If
the reading was about 12 volts DC, there
may be a loose connection or cut wire
between the power switch and the vehicle
half of the four way plug.
4. TO CHECK THE DOOR SWITCH:
Connect the voltmeter between the RED wire
from the vehicle half of the four-way plug
and the BROWN wire in the same plug (See
Figure 6). The reading should be about 12
volts DC when the door is open and zero
when the door is closed. If the reading is zero
with the door open, check the ground
connection from the door switch. This
connection should be clean and tight. See
Step #8 of the HOOKUP PROCEDURE. An
improper ground can cause intermittent or
erratic operation of the step. If the step will
not retract after being extended or extends
with the door closed, the BROWN wire to
the door switch may be touching a grounded
surface inside the wall behind the doorjamb,
or the door switch terminals may be touching
a grounded surface or each other. If the step
extends and retracts by its self while
traveling, check the conditions previously
described. With plunger door switches, be
sure that the door switch plunger is depressed
at least two thirds of its travel when the door
is closed. If the switch is not depressed at
least two thirds of its travel, it is possible for
the switch to make intermittent contact as the
vehicle frame shifts slightly while traveling
alone, the roadway. With magnetic door
switches, be sure the magnet is in place and
proper clearance is maintained between the
switch and magnet. If all the previous
conditions check okay, the door switch may
be faulty.
5. TO CHECK THE IGNITION SAFETY SYSTEM: Connect the voltmeter between the YELLOW wire
from the vehicle half of the four way plug and the ring terminal on the green ground wire (See Figure 7).
The reading should be about 12 volts DC when
