XPA Xtreme Electronic Power Assist
5.7 Wiring the Electrical
Connections
WARNING: ELECTRICAL SHOCK, FIRE,
EXPLOSION, AND/OR LOSS OF STEERING
CONTROL HAZARD. Failure to obey the
following warnings could result in death or
serious injury:
• Always use ABYC compliant components in electrical
installations of the XPA and any other electrical device
being installed on board the boat.
• Always use appropriate wiring terminals as per ABYC
requirements.
• Any electrical harness less than 72 in. (183 cm) in total
length does not require an over-current protection
device as per ABYC E11.10 over-current protection.
Any harness length exceeding 72 in. (183 cm) in total
length
must
use an over-current protection device as
per ABYC E11.10.
• If applicable, complete the wiring from the
distribution panel to the boat battery in accordance
with ABYC E-11.8 load calculation and E-11.15 system
wiring.
• When routing your electronic cables be careful to
avoid sharp turns and sharp edges.
• The XPA runs on a 40 A circuit and must be used with
either a 40 A fuse or circuit breaker.
• Do
not
attach any electric ground wires to the
helm. This will result in an electrolytic reaction to the
steering system that may result in system failure or
greatly reduced service life.
NOTICE:
The XPA should
never
be powered when
not properly mounted to a boat with the steering cable
correctly installed.
Consider the following:
• Use 16 AWG (1.3 mm
2
) wire to make any necessary
extensions.
• Use crimped Molex Perma-Seal (or equivalent)
butt splice connectors or shrink-sealed solder
connections.
• Locate all splices in a dry location and secure them
properly against mechanical damage.
The XPA is designed to operate on a 12 VDC power source .
Typical power source connections include:
– Direct to batteries
– To battery switches. (Never switch the negative
wire.)
– To a bus bar or power distribution panel. Ensure
the wire size from the bus to the batteries is
sufficient to handle the peak current of all devices
connected to the bus.
1. Turn off all power to the boat.
2. Identify a location for the status light installation on
the boat’s dash.
– The chosen location should be easily visible to the
operator when driving the boat in any position.
– Make sure that there are no obstructions behind
the dash where the light will be located.
3. Drill a 11/64 in. diameter hole into the dash at the
chosen location.
4. Install the LED status light into the hole.
5. Route the wire harness to the boat’s battery. Make
sure to not make hard turns or press the XPA wire
harness against sharp surfaces.
6. Install the 40 A XPA fuse holder according to the
instructions included in the kit. See “Optional Parts”
on page 4. Or install an ABYC E-11.10-compliant
40 A fuse or circuit breaker.
I
It is good electrical practice to protect all wire
harnesses with an over current protection
device.
7. Route the purple and gray wire to the dash.
8. Splice the purple ignition sensing wire of the XPA to
the boat’s ignition system wire. This wire must deliver
12 VDC when the ignition is “on” (key on).
I
If the purple wire is not connected, the system
will not operate.
9. Splice the gray wire to the yellow wire of the LED
status light and the light’s red wire to a 12 VDC power
source.
10. Connect the black wire from the harness to the
negative terminal of the battery.
