Milwaukee Allmand NIGHT-LITE PRO II Manual Del Operario página 29

C. The voltmeter should read 550 to 600 volts.
D. Turn off the light and shut down the engine.
E. If the voltage is not in this range, replace
the ballast transformer. See Replacing The
Ballast Transformer.
8. Check the capacitor:
A. Disconnect the red wire (E, Figure 34) and the
black wire (F, Figure 34) from the 2-port lever
locks.
B. Start the engine.
C. Using an AC voltmeter capable of safely
measuring up to 1,000 volts, connect one
probe of the voltmeter to the ground screw
where the green wire is connected (A, Figure
34), and the other probe to the output side
(white wire labeled "Lamp") on the capacitor
(G, Figure 34).
D. The voltmeter should read 360 to 440 volts.
E. Shut down the engine.
F. Re-connect the red wire (E, Figure 34) and
the black wire (F, Figure 34) to the 2-port lever
locks.
G. If the voltage is not in this range, replace the
capacitor. See Replacing the Capacitor.
9. Complete replacement of failed part(s).
10. Re-install the cover (D, Figure 34) with screws (C,
Figure 34).
11. Test the new ballast transformer and / or capacitor to
ensure proper operation.
Note: If you have difficulty in performing this
procedure, or if the results of this procedure do not
match those described, contact your Allmand Dealer,
or the Allmand Service Department.
Replacing the Capacitor
DANGER
Shock Hazard
Capacitors are capable of discharging high voltage that
will result in death or serious injury. Always turn off the
light switch, shut down the engine and allow capacitors
time to discharge before servicing.
Light tower trailers equipped with metal halide bulbs
require a ballast transformer and capacitor to operate.
See Specifications for the correct ballast transformer
and capacitor.
To replace the ballast capacitor:
1. Turn off the lights, and shut down the engine.
2. If the light tower is in the raised position, lower the
tower.
3. Allow capacitor time to discharge.
4. Determine which ballast corresponds with which
fixture.
Note: Figure 34 shows the items for light fixtures 1
and 2. Other fixtures are similar.
5. Remove the screws (C, Figure 34) and cover (D,
Figure 34) from the ballast box corresponding to the
affected fixture.
6. Remove the white wire labeled "Cap" (B, Figure 34)
and white wire labeled "Lamp" (G, Figure 34) from
the capacitor (H, Figure 34).
7. Remove the nut (J, Figure 34), washer (K, Figure
34), the capacitor clamp (L, Figure 34) and the
capacitor (H, Figure 34). Properly dispose of the
capacitor, following federal, state, local or province
environmental regulations.
8. Place the new capacitor (H, Figure 34) in the
capacitor clamp (L, Figure 34), and install on the
carriage bolt (M, Figure 34). Secure with nut (J,
Figure 34) and washer (K, Figure 34).
9. Re-connect the white wire labeled "Cap" (B, Figure
34) and white wire labeled "Lamp" (G, Figure 34)
from the capacitor (H, Figure 34).
10. Re-install the cover (D, Figure 34) with screws (C,
Figure 34).
11. Test the new capacitor to ensure proper operation.
Replacing the Ballast Transformer
Light tower trailers equipped with metal halide bulbs
require a ballast transformer and capacitor to operate.
See Specifications for the correct ballast transformer
and capacitor.
It is recommended that the ballast capacitor be replaced
at the same time as the ballast transformer to prevent
additional repair later on due to a failed capacitor.
To replace the ballast transformer:
1. Turn off the lights, and shut down the engine.
2. If the light tower is in the raised position, lower the
tower.
3. Allow capacitor time to discharge.
4. Determine which ballast corresponds with which
fixture.
Note: Figure 34 shows the items for light fixtures 1
and 2. Other fixtures are similar.
5. Remove the screws (C, Figure 34) and cover (D,
Figure 34) from the ballast box corresponding to the
affected fixture.
6. Remove the white wires from the ballast transformer
(I, Figure 34) labeled:
A. "Com" from the 3-port lever lock.
B. "Lamp" from the 2-port lever lock with the red
wire.
C. "120V" from the 2-port lever lock with the black
wire.
D. "Cap" from the capacitor (H, Figure 34).
