Clock Instructions; For Vfd Systems With A Clock Built In; Wiring - Dakota Digital 3 Series Installation And Operation Manual

Symptom
-----------------------------------------------------------------------------------------------------------------------------------
The Check Engine
indicator stays on
all of the time.
The Function switches
do not operate
properly.
The display system starts
up in the demonstration
mode and remains in it.
If you purchased your instrument system with a clock built in, it must be wired separately. The clock
displays the current time in 12 hour format. The digital clock from Dakota Digital incorporates the reliability and
quality of our standard gauges. These features include:
•
Quartz accuracy
•
Night dimming feature
•
Very low standby power to prevent battery drain
•
High visibility VFD display for sunlight readability

Wiring:

Clock
Operation:
The gauge needs the red, orange, and black wires connected to operate. The red wire should have
switched 12 volt power from an ACC. point on the fuse panel. The orange wire should have constant 12 volt
power. The black wire should be connected to a good ground point. When the blue wire has 12 volts, it will dim the
display for night viewing, this may be wired along with the wire to the DIM terminal on the control box.
Possible Problem
The Engine Control Module
(ECM) needs to see the
load of a light connected to it.
The push-button switches are
not connected to the control
box.
The wrong type of switch is
being used.
SW2 terminal is constantly
connected to ground.
