Installation & Start Up
ATP Helm Display not
illuminating
As soon as power and ground are
connected to the ATP display, the
display will flash the LEDs, starting
from the outside corners and moving
toward the center. If LEDs are not
seen flashing when power is applied,
no power is supplied to the
ATP Display.
• Potential Cause 1: There is no
power to the ATP Helm Display
orange wire.
• Solution: Check for power
connection to the ATP Helm
Display to ensure it is turned
ON. This should normally be
the same power source as the
helm instrumentation.
• Potential Cause 2: There is no
ground connection to the ATP
Helm Display black wire.
• Solution: Check for a
ground connection.
• Potential Cause 3: The ATP
Helm Display has been dimmed
to the off position.
• Solution: Press the SUN
button several times to
brighten the display.
• Potential Cause 4: The fuse
may be blown on the ATP Helm
Display.
• Solution: Check the fuse at
the ATP Helm Display. The
fuse should be 1.5A.

communication between the ATP
Helm Display and the
Control Unit.
• Solution a: Verify that the

is not flashing, there is no
communication between the
ATP Helm Display and the
ATP Control Unit.
• Solution b: Verify that
the ATP Helm Display
communications cable
is connected to the
communications cable on
the ATP Control Unit . An
