Medallion Gauges Quick Reference Guide

Overview:
Medallion gauges are digital instruments that use CAN data to deliver extremely accurate engine
information. They are connected directly to the engine's computer using one of the following data
streams:
x
J1939
x
NMEA 2000
x
SmartCraft
Each set of gauges has a harness that connects all of the gauges together and to the incoming data. The
tachometer is the "brain" of the system. It processes all of the incoming information and then
distributes specific data downstream to the other gauges.
Backlighting is controlled from either the Nav/Anchor light switch or the Panel Lights switch.
Some of the data does not come from the engine.
x
Pitot speed comes from the pitot tube connected at the outdrive up to a pitot sensor mounted
to the engine (Mercury DTS) or to the gauge harness (all others). This does not apply to boats
without speedometers.
x
Fuel level – Non DTS/EVC Engines: Comes directly from the fuel tank sender to an input wire on
the gauge harness.
x
Fuel level – DTS/EVC Engines: A unique Mercury or Volvo harness plugs into the back of the
engine and runs to the fuel sender (pink signal wire ONLY...ground for sender goes to boat
ground). Fuel level is processed by engine computer with the other CAN data.
x
Fuel level calibration – Volvo EVC only: If the fuel level calibration is missing on a Volvo EVC
engine, the 2.5" display will show dashed lines (
the Medallion system until the Volvo fuel system has been calibrated. If the fuel tank calibration
has been lost, it will be necessary to go into Settings and set the empty tank level, the fuel tank
capacity and perform a multi point fuel calibration. In some installations, it may be easier to
connect an extra fuel sender to the sender wires rather than remove the sender. Note that all
Monterey fuel tanks are either rectangular in cross section or very close to rectangular which
means that all fuel senders read linearly. The calibration process will ask for 20/40/60/80/100%
increments which can be measured along the length of any fuel sender regardless of length.
x
Air temperature comes from a sensor connected to the gauge harness
x
Depth and water temperature come from the transducer (if equipped).
x
Voltage is detected from power delivered at the helm and connected to the harness.
