If this is on the radar screen, you'll have to set your heading alignment on your radar. The radar may be 180 degrees out. if this occurs on the plotter, then if you have a heading sensor attached or an autopilot, your heading may be off.

Furuno 1715 gives "no heading pulse" error. Image normal, but clocked due to no reference. Pulled heading sensor (4X6X1mm black box, two wires, labeled NRS-101) and checked continuity across leads. Open...


Heading pulse is a reed switch sensor built inside the dome. upon each rotation of the array the reed switch is activated. Do a visual inspection of your array (inside) to make sure it is spinning (verify from a distance). Don't get eye level with the rotating array it can cause great harm to your eyes. Normally I have seen the belt slip off and also the lanyard attachment get caught in the array. Check those two things as well.

Ais and 1920c Furuno chart plotter


n the system setup, under “UNITS” I set BEARING to “MAG” (magnetic). This will cause the unit to display course / bearing information in relation to the Magnetic North and match magnetic compass readings. It is not the same as True North! One has to be careful with this setting. There are a number of areas where the earth's magnetic field is locally disturbed, sometimes very significantly. Your GPS may not account for it. - again, under “UNITS” I set “METRIC”.

Our Radar Furuno 1715-24NM On. ( Power in Oke ) but can not show drawing in monitor/lcd. thanks. regard - damanik


If you have no radar targets, go to longest range 24 miles, gain full, rain and sea minimum, do you have noise, if so, need magnetron, if not, need cable from display to dome.

My radar displays all contacts reverse. How do I get the display reversed? model #1731


I agree with Nico-Fixus, the heading alignment is one of the things to be checked. Unless this is a new installation it is unlikely that the Radome (antenna) got removed and reinstalled facing the wrong way. So antenna orientation would not be a concern.

I have seen units that for some reason the wrong Radome was selected in the configuration of the Navnet display.

Read the model number on the Antenna, then check that correct antenna type in loaded in your display.

Furuno 1715 Radar - 'NO HEADING PULSE'


More than likely the belt has come off again. This is a common problem with this radar. You'll need a small allen wrench to tighten it up again.

Furuno Radar Model 1833C


You have two things that orient the radar, on is called heading (or bearing) alignment. This is where you aim your radar so that a target comes up at 12 o'clock when dead ahead. Access this mode by pressing and holding menu duing power on, and go in to Installation Mode, radar setup, next page, align heading. I have posted a "tip" on this, search for VX2 radar alignment.
After this is done, North up is accomplished by having a magnetic input (fluxgate compass or autopilot). Calibration of this compass varies, but if it is accurate, then all should line up nicely.

No Sirius Weather Hot Page ICON


You will need to add the hotpage. do it like you're customizing your hotpages. Now if you're using Navionics then you will need to convert your unit to C-map. I know of a company in MD that can do this for you. The conversion process will remove your radar heading alignment and tuning setting though. Try www.mid-shore-electronics.com. They will be able to help you. They help me out alot.
