Ignition sensing
The Electric Actuator harness has a single purple ignition-sensing wire that
must be connected to an ignition source (has system voltage when ignition
is on). This wire provides the wake-up signal to the Electric Actuator; the
steering system will not work without it.
NOTE: Multi-engine applications
The electric steering actuators also receive a wake-up signal over the
CAN1 network, so both actuators will be on as long as one of the ignition-
sensing wires has a signal. You must still connect both sensing wires.
Important wiring requirements
• The ignition-sensing wire must be routed in such a way that it is
protected from physical damage, water, and high temperatures over its
entire length. Incidental splashing water is okay but avoid immersion or
prolonged spray. Never put splices in a wet area.
• Use tie-wraps or other strain-relief devices on either side of any splice
and at the final connection point. If someone inadvertently pulls on the
wire anywhere in its travel it must not pull any splice or connection apart.
• Use sealed, heat-shrink butt splices, such as Molex Perma-Seal, or a
soldered connection with heat-shrink tubing. Follow the manufacturer’s
instructions to ensure a proper splice.
Ignition source options
On most boats you will have one of two options for an ignition source: you
can connect to a single ignition source wire, or you will have to splice into
an existing ignition wire.
DANGER!
The integrity of the ignition-sensing circuit is critical to the safe operation
of the steering system. Follow these instructions carefully. Failure of the
ignition-sensing circuit will result in loss of steering control, which could
lead to a collision and/or ejection from the boat, causing property
damage, personal injury, and/or death.
