TROUBLESHOOTING
Testing the
system with
all connected.
Use a volt/ohm meter set to DC Voltage. Measure from ground to each color wire,
of the
MCU
(Master Controller) going out to the light. The voltage should read
between 8 to 10 Volts DC, when the point pad is activated. If, for example, you
want to check the elevation, measure on the RED and WHITE when the Point pad
is pressed
to „down‟. There should be 8-10 V on one of these wires.
Motion is OK,
but no light
Disconnect the
YELLOW
and
GREEN
wires (in the 6-wire wiring harness leading
out of the Master Controller) and connect the 12V battery test wires to the
yellow
and
green
wires
LEADING TO THE LIGHT
. If the lamps do not light up, check the
continuity of the yellow and green wires and any splices or terminal connections
through the harness to the searchlight. If the continuity tests OK, the bulbs must be
checked. Do the following:
Please do not try to test the bulbs with a tester/ohm meter as you would a normal
incandescent house bulb. Remove (without touching the bulb with your hand) the
bulb from the socket and connect the leads to a 6V battery to test them. If the
bulbs test good, check for corrosion on the brush assembly mounted at the bottom
of the housing, or on the slip ring assembly mounted in the base.
If there is corrosion on either the brush or slip ring assemblies, gently clean it off
with a
fine
wire brush or sanding paper and wipe clean with rubbing alcohol. If the
slip ring assembly is pitted, it will need to be replaced.
If the brush and slip ring are OK, and the lamps light up when connected to the
battery, the
MCU
(Master control unit) needs to be replaced.
No up and
down,
everything
else is OK
Disconnect the
RED
and
WHITE
wires (in the 6-wire wiring harness leading out of
the Master Controller) and connect the 12V battery test wires to the
red
and
white
wires
LEADING TO THE LIGHT
. The light should move either up or down. If you
change the POLARITY it should move the other way. If this happens without a
problem, the
MCU
(Master control unit) is faulty and needs to be replaced. If not,
do the following:
