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.
