MOUNTING
The MCL-4000 series gauge requires a round hole 1-7/8” diameter. It should be inserted into the opening from
the front and the U-clamp will be installed from the back. Tighten the two nuts on the U-clamp so that the gauge is secure.
Gauge depth to the back of the case is approximately 1-3/8”. Gauge depth including the mounting studs is about 2-1/8”.
TEMPERATURE GAUGE SETUP
The green wire in the harness is used to enter setup and change/select settings. This is done by
powering the green wire with +12V or releasing it. To power the green wire, touch the wire to a +12V source.
To release the wire, remove the green wire from the source. The gauge moves through the setup in the
following order: Software code > Sender selection > High temperature warning > done
default settings: 30F (SEN-1041) 202°F high wa rning point
1. Make sure the key is off so the gauge is not powered.
2. Power the green wire while turning the key on.
3. The display will show “Lt1“, this is the software code. (Newer software versions may have a different code.)
4. Release the green wire. The display will read “Snd” (temperature sender selection).
5. Power and release the green wire. The currently selected temperature sender type is displayed. The
options are as follows:
“30F” °F SEN-1041 “15C” °C SEN-1041
“40F” °F SEN-1043 “20C” °C SEN-1043
“29F” °F SEN-1044 “14C” °C SEN-1044
6. Power and release the green wire until your temperature sender is displayed.
7. Power and hold power to the green wire to store the sender setting.

8. “HI” (high temperature warning) will be displayed. Release green wire.
9. Power and release the green wire to adjust the high temperature warning point.
10. Power and hold power to the green wire to store the high temperature warning point.
POWER RED WIRE
Connect the red wire from the main harness to accessory power from the ignition switch.
Never connect this to a battery charger alone. It needs to have a 12 volt battery connected to it. Battery chargers
have an unregulated voltage output that will cause the system to not operate properly.
GROUND BLACK WIRE AND RING TERMINAL
The black wire is the main ground for the gauge. A poor ground connection can cause improper or erratic
operation. Connect the ring terminal to one of the mounting studs after the clamp has been installed before the thumb nut
is screwed on to secure the gauge.
TEMPERATURE SENSOR GREY WIRE
The gray wire connects to the temperature sensor. DO NOT use Teflon tape on the sender threads as the sender
grounds through the threads to a body ground. Using Teflon tape will prevent body grounding and will cause an error in the
temperature reading. If the sender mounting prevents body grounding (i.e. mounting into plastic fittings) a grounding wire
will need to be clamped to the body of the sender and connected to a good ground.
FUNCTION WIRE GREEN WIRE
The function wire (green wire) is used to change settings on the gauge as described above in the setup section.
This is done by touching and removing the wire to +12V.
NIGHT DIMMING BLUE WIRE
Your display system has a dimming feature that reduces the display intensity. Normally the system is at full
brightness for daytime viewing. When the blue wire has 12 volts the display intensity will be reduced. The blue wire can be
connected to +12v through a switch to allow the dimming feature to be turned on or off. To have the system at full
brightness all of the time, leave the blue wire disconnected.
TROUBLESHOOTING GUIDE
Problem Possible cause Solution
Gauge will not light up. Red wire does not have power.
Black wire is not getting a good ground.
Gauge is damaged.
Connect to a location that has power.
Connect ground to a different location.
Return gauge for repair.
Gauge displays or flashes
“EEE”.
Gray wire is not connected properly.
Sender has poor / no ground.
Temperature is lower than range of
sensor.
Check connection from gray wire to sender.
Check for good sender ground, remove any sealant
tape for the threads of sender.
This occurs at temperatures below freezing. Once in
range, correct temperature will be displayed.
Gauge displays or flashes
“---“. Grey wire is shorted to ground.
Temperature is above range of sender.
Check grey wire for breaks in insulation or pinched
areas.
Take action to prevent further heating. If common
problem, use higher temperature sender.
Gauge always flashes. High warning point set too low. Adjust the high warning point using the setup menu.
Gauge will not dim. Blue wire is not connected correctly. Check wiring. Blue wire should have 12 volts when
dimming is desired.
Gauge remains dim at all times. Blue wire is getting power all of the time. Connect blue wire to +12v through a switch or leave
unconnected.
Gauge will not go into the
SETUP mode. Green wire is not powered at key on. Make sure to touch the green wire to a +12V source when turning on key.
Check to make sure the point where the green wire
is touched does have +12V using a voltmeter.
Gauge displays “Er” followed by
a number or letter. Some of the setup data has been lost or corrupted. Reset all settings in the SETUP menu to ensure they are correct.
Gauge does not read correctly. Incorrect sender type selected. Select correct sender type using SETUP menu.
