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. Remove front cover from the trailer.
5. Determine which ballast corresponds with which fixture.
Note: Figure 28 shows the items for light fixture 3. Other
fixtures are similar.
6. Remove the screws (C, Figure 28) and cover (D) from the
ballast box corresponding to the affected fixture.
7. Remove the white wire labeled "Cap" (B, Figure 28) and
white wire labeled "Lamp" (G) from the capacitor (H).
8. Remove the nut (J, Figure 28), washer (K), the capacitor
clamp (L) and the capacitor (H). Properly dispose of
the capacitor, following federal, state, local or province
environmental regulations.

9. Place the new capacitor (H, Figure 28) in the capacitor
clamp (L), and install on the carriage bolt (M). Secure with
nut (J) and washer (K).
10. Re-connect the white wire labeled "Cap" (B, Figure 28)
and white wire labeled "Lamp" (G) from the capacitor (H).
11. Re-install the cover (D, Figure 28) with screws (C).
12. Re-Install the front cover to the trailer.
13. 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. Remove front cover from the trailer.
5. Determine which ballast corresponds with which fixture.
Note: Figure 28 shows the items for light fixture 3. Other
fixtures are similar.
6. Remove the screws (C, Figure 28) and cover (D) from the
ballast box corresponding to the affected fixture.
7. Remove the white wires from the ballast transformer (I,
Figure 28) labeled:
1. "Com" from the 3-port lever lock.
2. "Lamp" from the 2-port lever lock with the red wire.
3. "120V" from the 2-port lever lock with the black wire.
4. "Cap" from the capacitor (H, Figure 28).
8. Remove the nuts (N, Figure 28), washers (O), screws
(P), the green ground wire and the ballast transformer
(I). Properly dispose of the transformer following federal,
state, local or province environmental regulations.
9. Install a new ballast transformer (I, Figure 28) using
screws (P), nuts (N), washers (O). Install green ground
wire as well.
10. Connect the white wires from the ballast transformer (I,
Figure 28) labeled:
1. "Com" to the 3-port lever lock.
2. "Lamp" to the 2-port lever lock with the red wire.
3. "120V" to the 2-port lever lock with the black wire.
4. "Cap" to the capacitor (H, Figure 28).
11. If replacing the ballast capacitor, replace at this time. See
steps 3 through 9 of Replacing the Capacitor .
12. Re-install the cover (D, Figure 28) with screws (C).
13. Re-Install the front cover to the trailer.
