NorthStar Navigation 438, 435 operation manual Fuel used or remaining seem inaccurate

Page 30

9. Fuel used or remaining seem inaccurate:

a)If the engine is run while the fishfinder is powered off, the fishfinder does not record the amount of fuel used during that engine run. Consequently, the Fuel remaining value will be higher than the actual amount of fuel remaining in the tank.

To avoid this problem, use the Auto Power Wiring option described in section 6-4 Wiring options. This ensures that the fishfinder powers on automatically whenever the boat’s ignition is switched on.

b)In rough seas, fuel may surge back and forth through the fuel transducer, resulting in incorrect readings. Try installing a one-way valve between the fuel transducer and the fuel tank.

c)The Set remaining fuel value must be reset after every refuelling (see section 3-3 Setup > Fuel).

d)The fuel tank may not refill to the same capacity each time due to air pockets. This is particularly noticable with underfloor tanks.

e)Fuel transducers wear out over time and should be replaced after every 5000 litres of fuel.

10. Flow indicates no fuel or low fuel:

a)Check that the number of engines is set to 1. See section 3-3 Setup > Fuel.

b)Check that the fuel cable connectors are securely plugged in and the collar is locked in place. The collar must be locked in place to give a watertight connection.

c)A fuel transducer may be clogged. If so, remove the transducer from the fuel line and gently blow through it in the opposite direction to the fuel flow.

A fuel filter between the fuel transducer and the fuel tank must be installed as per the fuel installation guide. Failure to do so will void the warranty.

d)Inspect the fuel cable from end to end for damage such as cuts, breaks, trapped or squashed sections.

e)Check that the fuel filter is clean.

11.A twin engine installation shows only one flow rate:

a)Check that the number of engines is set to 2. See section 3-3 Setup > Fuel.

12. Erratic Fuel Flow readings:

a)The fuel flow transducer may have been mounted too close to the fuel pump or may be subject to excessive vibration. Refer to the installation instructions supplied with the fuel transducer.

b)Check for leaks in the fuel line or in the fuel pickup in the tank.

c)The Flow filter value is not suitable for the engine. Check that the value is not set to zero, then try increasing the value until a steady flow rate is shown. See section 3-3 Setup > Fuel.

13. There is no reading for fuel economy:

a)The boat must be travelling through the water to generate an Economy reading.

b)Check that the paddlewheel on the transducer is spinning freely and that the two magnets in the paddlewheel are still in place.

14. There is a double bottom trace displayed:

a)The boat may be in an area that generates shadows. See section 4-1 Interpreting the display.

b)In shallow water, the echoes may bounce. Reduce the gain setting (see section 4-3 Gain).

c)Decrease the Range.
