INSTALLATION GUIDE
LED CoPilot Voltmeter Gauge w/Alarm
Part Number: C 9015
- Always disconnect the battery before attempting any electrical work on your vehicle.*
KIT COMPONENTS
- One (1) C9015 CoPilot LED Gauge 2 ⅝ in. diameter, plus bezel and mounting bracket
SPECIFICATIONS
- This gauge reads voltage output from 7 to 18 volts, (in tenths) with two visual alarm LED lights that will warn if the voltage goes either above or below the pre-set limits. There are two buttons on the lower face of the gauge to enable these settings: one is for low and the other is high.
WIRING INSTRUCTIONS – Gauge
Note: Automotive circuit connectors are the preferred method of
connecting wires. However, you may solder if you prefer.
Ground – Black Connect directly to an engine ground such as the engine block.
Power – Red Connect to a switched +12V source such as the ignition switch.
Dimmer – Purple Connect to the parking lights to dim the LEDs 50% when the
headlights are on.
However, do not connect to the headlight rheostat control wire; the dimming
feature will not work properly.
Otherwise, connect to ground for permanent 100% brightness.
Ground Output – Gray NC if between limits Connect to the ground unless you
exceed limits.
Ground Input – Blue NO Connect to the ground of the device to be controlled.
OPERATION
Voltage – Controlled Ground Switch
This device has two settings for Normally Open (the Blue wire will provide
ground AFTER the switch reaches the set voltage), and for Normally Closed (the
Blue wire will provide ground UNTIL the switch reaches the set voltage).
Activation is at 7v Normally Open. The display will stay in Settings Mode
until it is programmed. To program the unit after starting the engine, shut
the engine off and turn on only the ignition.
Reads in tenths
While in Settings Mode, use the push buttons on the device face to change the
voltage switch settings in increments of .1 at a time, up to a maximum of 18v.
The left button increases, while the right button decreases. Once you are at
the desired setting, the LED display will stay on the desired voltage setting
for a few seconds, then switch to NO and NC settings. Use the left button to
choose. After the engine is turned off, the settings will remain in memory,
until they are manually changed, as described above.
If voltage is below low limit or above high limit settings, display and light
will flash. Output will be pulled to ground for Normally Open settings, above
ground for Normally Open setting.
To Re-Calibrate
If, at any time, you wish to change the settings, press both buttons until you
see “CAL” displayed.
Release buttons. Edit displayed voltage up and down, using the buttons, to
desired settings. The display will be blank, then will show the new measured
voltage.
