Connecting Power
The Bambi Bucket requires a 24 VDC power source capable of supplying 5 A.
There are four types of suggested wiring installations (see Section 10: Drawings ):
1. Pilot control: The control is wired into the pilot’s control column through a relay.
2. Pilot control (US InterAgency): The control is wired into the pilot’s control column through
a 50 ampere relay as per US interagency regulations. This system can also be used to control
a heli-torch, etc.
3. Crew control: A crew member or pilot controls the dumping of the bucket using power from
the helicopter and a remote switch.
4. Crew control (remote power supply): A crew member or the pilot controls the dumping of
the bucket using a battery pack to supply the power to the remote switch.
The Bambi Bucket’s electrical supply is connected through a breakaway plug. The purpose of the plug is
to offer a clean “breakaway” if the Bambi Bucket has to be jettisoned from the aircraft in an emergency.
To ensure that wind action does not separate the plug, it is suggested that the plug be lightly taped
together with vinyl tape while in use.
To check for continuity in the connections, push the momentary contact switch. A clicking sound should
be heard from the control head.
NOTICE
To operate the solenoid and release the water, a momentary contact switch is used. The solenoid has a
10% duty cycle. Operating the solenoid continuously will result in solenoid failure.
Longlines
NOTICE
If using a longline, the minimum recommended length is 50 ft (15 m).
When using a longline, select the correct gauge of control cable from the following chart.

When using a synthetic rope longline, it is recommended that a protective cover be used and the control
cable be inserted at the time of manufacture. However, if this is not feasible, it is recommended to secure
the cable using tape at 3 ft (1 m) intervals along the longline. It is not recommended to use zip ties as
they tend to damage the cover and longline. When attaching the control cable, allowances must be made
for any stretch in the load bearing line. When the control cable is taped to the outside of the longline, the
flight characteristics can change.
