We’ve all been there. The deck of your boat is torn apart and something isn’t working, but what is it? Have no fear! We will guide you on how to test both your KUS liquid level sending unit and gauge so that you can isolate the problem and quickly order a new part.


Troubleshooting Your KUS Gauge

  1. Make sure you have 12 Volts DC going to your gauge (red wire), and that your gauge is grounded (blue wire). and either one (1) or both light options (yellow and orange wires) are connected to power as well. [For gauge specific wiring instructions please see the product data sheets]
  2. To check the gauge operation / movement:
    1. Make sure the Power to the gauge is not on.
    2. Disconnect the black wire to the sending unit, at the gauge end. Note, you may have to cut the wire (you can always re-connect it later). Leave enough wire at the gauge end to work with. Do not cut it too short.
    3. With the black wire disconnected, turn the 12 VDC power to the gauge ON

The gauge needle, will:

      1. On the American version gauge (240-30 ohms), stay at Empty. Ground the black wire (at the gauge end), and the needle will go to Full.
      2. On the European version gauge (0-180 ohms), go to Full. Ground the black wire (at the gauge end), and the needle will go to Empty.

If the above-mentioned test is successful, there is nothing wrong with the gauge.

If it is not successful, replace the gauge.


CP2 (2 Tank) Gauge Troubleshooting

Note, the wiring for the 2 tank gauge panel is identical to the single tank gauge set-up (listed above), with exception to the amount of black wires. On the two (2) tank gauge panel, there are two (2) black wires, one (1) wire for each of the sending unit black wires.

Check all your solder connections on the panel switch. This is a three (3) position toggle switch. Ensure that there is a solid click to each of the 3 stations.

Following the steps above, check your gauge operation and movement.


CP7-B (7 Tank) Gauge Troubleshooting

On the back of 7 tank gauge panel, the wiring that comes out of the back of the gauge (5 wires – black, blue, red, yellow and orange) to the top of the PCB board, should not be tampered with.

The red wire that comes out from the gauge should go to a 12 Volt DC power source.

The black wire (that comes out from the gauge in the same area as the red), should go to ground.

The 7 tabs, on the back of the panel are for each one of your tanks. The black wire from each individual sending unit should be hooked to one (1) of these tabs. It is not necessary to use all 7 tabs.

Following the steps above, check your gauge operation and movement.

1 EXTREME CAUTION SHOULD BE EXERCISED WHEN DEALING WITH FUEL TANKS.

If you are at all unsure of your capabilities to perform this function safely, have a Marine Repair

Facility, or Boat Dealership Service Dept. perform this function. Also please note that the five (5) mounting screws will only line up one (1) way. Mark the lead hole with the tank. Our sending unit lead hole is 180 degrees from the wire exit (opposite).


KUS Gauge Instrumentation

Analog

Fuel Level

The SeaV Series are boat builders go to gauge series for their simplicity and wide variety of different gauge options.

The SeaV series features an IP67 protection rating allowing the gauge to work up to one meter underwater, double layer reinforced anti-fog glass to prevent fogging in humid conditions, easy installation with a multi-plug socket connection design, and selection of red or yellow back-light for your choice.

Digital

NMEA Tachometer - NMHB

The SeaN Series offers easy plug-and-play installation to the NMEA 2000 network while maintaining a clean classic design.

The SeaN series consists of seven single function gauges, and a Integrated Tachometer that also shows real time performance data, such as battery status, engine temperature, oil pressure, and fuel consumption rate.

KMG Button

The KMG Touch/Button gauge is a multifunctional digital instrument developed specifically for boats, yachts, and marine applications. The instrument integrates major functions such as fuel level, oil pressure, tachometer, speedometer, and oil and water temperature all in one device.

The robust and compact design allows users to have more important information available at the same time. The instrument comes in a stainless-steel cover with a black dial and two styles of display interfaces, touch screen or button, to meet your different requirements.

KMB-70

The KMB-70 Series is an Integrated Data Monitor with an advanced TFT (Thin Film Transistor) screen. The KMB-70 displays real time network information including engine output, fluid levels, and speed. KUS can also customize the unit to meet customer requirements. The unit is compatible with J1939 and NMEA 2000 systems.

The KMB-70 is a perfect fit for marine applications that monitor information over the J1939 or NMEA 2000 network.

KMB-43

The KMB-43 Series is an Integrated Data Monitor with an advanced TFT (Thin Film Transistor) screen. The KMB-43 displays real time network information including engine output, fluid levels, and speed. KUS can also customize the unit to meet customer requirements. The unit is compatible with J1939 and NMEA 2000 systems.

The KMB-43 is a perfect fit for marine applications that monitor information over the J1939 or NMEA 2000 network

Panel

CP2-F

The CP-2 allows the user to monitor multiple tanks levels without the need of multiple gauges, thereby saving precious dashboard space.

The CP-2 allows the user to toggle between and monitor two tanks by a flip of a switch.

CP7-B

The CP7-B allows the user to monitor multiple tanks levels without the need of multiple gauges, thereby saving precious dashboard space.

The CP7-B allows the user to toggle between and monitor up to seven tanks by press of a button.
