ATTENTION Prior to installation, please make sure you have the following items:

1 Display

1 Control box

1 Main power cable

1 Data cable

1 Tachometer cable with resistor

2 Pressure sensor wires, 78.5” long

2 Pressure sensors

2 Sensor connectors, 78.5” long

2 Temperature sensors

1 Package mounting hardware

INSTALLATION

PHYSICAL MOUNTING

Install instrument into panel cutout using supplied screws. Since hardware is self locking, back off ¼

turn after tight to prevent cracking of plastic face-plate. Be sure to mount the instrument directly in

front of the pilot, shaded from the sun for best viewing. Install the sensor box inside the aircraft, not in

the hot engine compartment

POWERING UP / PREPARING CABLES

The Cables supplied are crimped but not soldered. The option is there for you to use a small soldering

iron and solder every connection prior installation for an even more secure connection. Plug power

wire into sensor box. Wire white and red wire together to avionics power bus 12V. Use 1A fuse or

breaker. Do NOT leave instrument on during engine cranking.

GROUND

The Viking View Instrument ground wire MUST be from an electrically quiet source. Grounding the

instrument to the battery or avionics bus ground will cause for an erratic tachometer reading.

For engines sold after September 2016, there is a green with white stripe instrument ground wire

supplied in the engine ECU wire loom. It is now labeled VKG View or Viking View (Be sure NOT to

use this for anything else and never ground this wire. Cap off the end if not used)

For earlier engines, the ground can be sourced from the engine coolant temperature probe at the ECU

end of the same wire. The above picture shows the wires of the coolant temp ground wire by the ECU.

The wire will be all black or all white. Remove some protective loom, used a razor blade, and carefully

remove some wire insulation. Do this about 10” from the connector. Solder a wire to the exposed area

and reseal with quality electrical tape. This is only if you don’t already have a green with white stripe

instrument ground wire.

GEARBOX PROBE

Install gearbox oil temp probe. It is displayed as “Oil Temp” on Viking View instrument. Use Teflon

thread sealant. Connect to Viking View control box with supplied cable, being VERY careful with the

delicate sensor cables. Never pull on the wires, just the connectors. Strain relief each side of the

connectors to prevent them from separating

COOLANT TEMP

The coolant temp is identical and is installed behind the gearbox on top on the 130 engine. Remove

the small Allen plug and install sensor using an extended 3/16 allen wrench. The location is somewhat

difficult and some builders have just removed the small cast housing from the engine, using a 10mm

wrench, installed the sensor on the bench, and then reinstalled the housing using gasket cement. (We

use the Permatex “RightStuff”)

OIL PRESSURE

Can be installed straight or with 90 or 45 degree fitting on the back of the engine

OPERATION

Plug in all sensors and power. Turn on power. Instrument should light up and display:

RPM, Coolant temp, Oil temp of gearbox, Oil pressure, Fuel Pressure.

If an X appears, the connection to that probe is faulty. Recheck wiring and reboot instrument.

LIMITS

RPM – TURNS YELLOW WARNING AT 6000 RPM

OIL TEMP OF GEARBOX – YELLOW WARNING AT 230 F

COOLANT TEMP – YELLOW WARNING AT 230

OIL PRESSURE – YELLOW WARNING BELOW 20 PSI
