Technical Trouble Shooting
Q: Why is the level gauge reading backwards (reading full when tank should be empty, reading empty when tank should be full)?
  • That means the gauge and the sending unit are using different standards (one may be using American standard, 240 ohm at empty, 33 ohms at full; the other may be using European standard, 0 ohms empty, 190 ohms at full), hence, are not compatible.
  • Only solution would be to replace either the gauge or the sending unit so that both are using either European Standard or American Standard ohm range.
Q: Does Wema carry a fuel sender that can be shortened in length?
  • Yes, the length of the High Resolution Capacitance Level Sensor (CLS) can be shortened and signal output re-calibrated.
Q: What lengths do the standard units come in?
    • Available 4" through 18.5" at 0.5" increments
    • Available 19" through 60" at 1" increments
  • S3U and S5U
    • Available 4" through 60" at 1" increments
    • 4", 6", 8", 12", 16", 18", 20", 22", 24", 28", 38"
Q: Are the level senders or gauges NMEA 2000 certified or compatible?
  • Currently the gauges are not compatible with the NMEA 2000 system. The level senders can be made compatible by connecting it to a signal converter module.
Q: What are the input signals for the gauges?
  • The signal input for our stock gauges are 240-33 ohms American Standard and 0-190 ohms, European Standards
Q: What type of signals does the Tachometer take?
  • The tachometer can process both sine and square signals.
Q: What is the operating voltage for the gauges?
  • The gauge can work with both 12V and 24V systems. When connecting to a 24V system, certain gauge will require a drop resistor on the connection between the power and the gauge.
Q: How to test if the level gauge is operating correctly?
  • Make sure power to the gauge is not on.
  • Disconnect the black wire on the gauge to the sender. Leave enough wire at the gauge end to work with.
  • Turn on the power to the gauge
  • Inspect the
    • American standard gauges (240-30 ohms) will show Empty. Ground the black wire, and the needle will go to Full
    • European standard gauges (0-180 ohms) will show Full. Ground the black wire, and the needle will go to Empty
Q: How come the Navigation Gauge is not working?
  • If you recently switch the bulb on your vessel from incandescent bulbs to the equivalent LED counterparts, you need to reconnect the wires from the B1-B5 terminal to the L1-L5 terminal. Please see attached instruction.
Q: Are the gauge dials backlit?
  • Yes, the gauge dials are backlit with LEDs.
Q: Do the gauges only work with Wema senders and sensors?
  • No, the gauges can work senders and sensors from other companies as long as both are compatible (both American standard units, or both European standard units).

This aggressive slice of supercar is the Lamborghini Gallardo LP570-4 Squadra Corse – making its debut here at the 2013 Frankfurt Motor Show, it could quite possibly be the last current-shape Gallardo variant we’ll ever see. Named after a famous breed of fighting bull (what else?), the Gallardo has been around for a decade now. Tweaks to the chassis, engine and styling over that time have kept it fresh, but could the Squadra Corse be a last hurrah for this Lamborghini?
