A. Remove transformer cover. Measure voltage
across terminals marked "C" and "H". (Refer
to appropriate wiring diagram in Section 4.)
Line voltage of 120 VAC or 240 VAC, as appli-
cable for model, should be present. If not pre-
sent, proceed to Section 3-I-B. If 120 VAC is
present, proceed to Section 3-I-C.
WARNING: Line voltage (120 VAC or 240 VAC, as ap-
plicable for model) is present on exposed
wiring.

voltage is present, fuse is blown. If voltage is
not present, the problem is external to the V
light. Check circuit breakers. DÌ
. Measure voltage across secondary terminals 4 y (SET SCREW
marked "0" and "25". If not 25 VAC (light NOT SHOWN)
burning) or 27 VAC (light not burning), trans-
former is bad. If voltage is present, proceed to
Section 3-|-D.
. Remove wire nuts at points 1 and 2 (located
inside post knuckle). (Refer to appropriate wir-
ing diagram in Section 4.) Attach a 4 ohm, 200
watt (or larger) resistor between yellow wires 1 NOT SHOWN)
and 2 and measure 25 VAC. If voltage is pre-
sent, proceed to Section 3-I-F. If voltage is

wires shorted, dimmer is defective and should
be replaced. If 25 VAC is not present, proceed
to Section 3-I-E.
NOTE: If column has roll pin already installed, roll pin
must be removed before disassembling.
WARNING: Disconnect electrical power supply while
disassembling. Failure to disconnect
electrical power may result in electrical
shock.
E. Use 1/8" pin punch to drive roll pin inside col-
umn.
. Remove light from column by removing set
screw and stop screw, and unscrew arm
mounting collar counterclockwise as viewed
from below (Figure 1). Pull phase control out
of column. If roll pin was driven into column,
locate and discard it. Disconnect Mate-n-Lok®
connector and measure voltage at pins 3 and
4. If 27 VAC is present, phase control is defec-
NOTE:
wires are broken or connector is
loose between transformer and bottom of col-
umn. Check and replace as necessary. After
completing checks, reinstall light on column.
When reinstalling column or column adapter,
realign hole and replace roll pin. If realign-
ment is not possible, redrill hole. Always use
a new roll pin to ensure safe installation.
G. Order Light Fantastic® Column Installation In-
structions (with roll pin), kit no. 025182.

H. Remove resistor and reattach yellow wires to
black wires. Remove yoke cap and measure
27 VAC across points 5 and 6. If no voltage is
present, wire in front arm is broken and (both)
should be replaced. If 27 VAC is present, pro-
ceed to Section 3-|-|.
Measure voltage between points 5 and 7. If no
voltage is present, ON/OFF switch is defective
and should be replaced. If 27 VAC is present,
proceed to Section 3-I-J.
. Remove lamp. Measure voltage across socket
contacts. If 27 VAC is present, lamp is defec-
tive or contacts are corroded, and should be
replaced or cleaned. If no voltage is present,
proceed to Section 3-I-K.
