Remove the four screws underneath the head of the light, to loosen the protection
cover. Gently lift the head from the base in order to view the brush and slip ring
assembly. If any corrosion is evident, gently clean the brush and slip ring
assemblies with a fine wire brush, taking care to wipe clean with a rag and rubbing
alcohol. If pitting has occurred on the slip ring, or if the brush assembly is
damaged, the unit must be sent in for repair. The service agent or owner can
replace the parts by ordering new ones. If these parts look OK, connect the leads
from the battery to both of the small pins on the brush assembly. The elevation
motor should turn. If you reverse the wires the motor should turn in the opposite
direction. If the motor does not turn with this test, then the elevation motor needs to
be replaced.
No left and
Disconnect the BLACK and BROWN wires (in the 6-wire wiring harness leading
right,
out of the Master Controller) and connect the 12V battery test wires to the black
everything
and brown wires LEADING TO THE LIGHT. The light should move either left or
else is OK
right. 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:
Remove the four screws underneath the head of the light, to loosen the protection
cover. Gently lift the head from the base in order to view the two plastic gears by
turning the head upside down to see them. If they are intact, the ROTATION motor
is faulty. Replace this motor.
If the planet gears are stripped, order new and install.
Lights work
First, disconnect the coaxial cable from the MCU and Point pad. With an ohm
but no
meter set to R x 1, check continuity of the coaxial cable by placing 1 probe to the
rotation or
connector shielding and the other to the center conductor. If the cable is good, you
elevation and
will get NO meter movement at all. If the cable is bad, you will get a full scale
lights will not
reading on any meter scale. If you get a full scale reading, replace the coaxial
shut off
cable connectors. If you get no reading, then the cable is OK. Turn off the circuit
breaker at the power source, wait 10 seconds and then turn the circuit back on.
This should reset the MCU. Re-check the functions and they should be cleared. If
you still experience the same problems, then the MCU will need to be replaced.
