One Series 95/96 NMEA 0183 Input Multifunction Meter
One Series 85/86 Pulse Output Multifunction Meter
To insure years of trouble-free operation, please read all of these
instructions carefully before beginning your installation
Your twin diesel kit contains one NMEA kit and one Pulse kit. The Pulse kit provides fuel flow information from the engine. It is
installed on to the NMEA head on the other engine. The twin kit comes with a special cable harness with all the cross connections
required between the two meters already made for you. Follow the electrical connection steps listed below after you have completed
the mechanical part of the installation. The twin install kit includes a wiring connection schematic, showing the NMEA unit on the
PORT side and the Pulse unit on the Starboard side. The meters are shown looking aft from the connector side of the meter. If you
want the NMEA head on the Starboard side, wherever you find Port write Starboard and vice versa.
All 95T/96T, 85T/86T kits come with the flow sensors labeled with the same serial number as the meter in the kit and are labeled as
Feed or Return flow. The serial numbers must stay with the meter they came with and must be installed in the fuel system as labeled.
Follow the steps below and make all the wiring connections to the instrument and engine on one side before proceeding to the
instrument and engine on the other side. This greatly reduces confusion and wiring problems. Turn OFF the power to your
instrument panel before beginning the electrical installation.
Installing the NMEA instrument (95, 96 Series)
1. Decide whether you want the MPG reading on the Port or the Starboard side of your instrument panel. If you have an existing
tachometer, label the signal lead(s) and remove the power + ground leads and the tachometer. Install the meter labeled on the
back “NMEA”. The lower left-hand window displays either GPH for this engine or total MPG.
2. Plug in the white connector labeled NMEA 0183 to the meter labeled “NMEA” and separate out the wires coming from this
connector.
3. See the tachometer section of the “Mechanical & Wiring Overview Installation” sheet (4001-325-00) for connection of the yellow
wire, terminal #8 and the violet wire, terminal #16.
4. The black wire (12”), terminal #5 (system ground) connects to the junction of the black wires from the feed and return flow
sensors and goes to battery ground. This instrument uses a single point ground system to reduce noise interference and must have
only one connection to battery ground.
5. The white wire, terminal #6 (signal) connects to the white wire of the feed flow sensor.
6. The brown wire, terminal #14 (signal) connects to the white wire of the return flow sensor.
7. The NMEA meter requires two switches, one for GPH-MPG and one for the Gallon reset.
Connected the black wire, terminal #13 to one of the terminals of the GPH-MPG switch and one of the terminals of the Gallons
reset switch. Connect the gray wire, terminal #2 to the other side of GPH-MPG switch. Mount the switch with ON in the UP
position. This puts the meter in MPG mode when the switch is up and GPH mode when the switch is down. Connect the green
wire, terminal #10 to the other side of the Gallons reset switch. This switch can be either a normally open momentary push
button or a spring-loaded toggle switch. Mount the switch with ON in the UP position. This puts the meter in the reset mode
when the switch is up.
8. See the NMEA 0183 wiring sheet (9000-011-00) for connection of the white/orange wire, terminal #15 and the green/black wire,
terminal #7.
9. Connect the red wire, terminal #1 to the engine ON side of the engine key switch.
