SOURCE: Furuno 1622 Radar dome spins inconsistently

This is a belt driven antenna. That would be the first thing to check, to be sure it’s not slipping. This should be easy to see if the motor is spinning but not the antenna that would be the problem.
I don’t recall if this model uses a “toothed belt” or not, but if it does check the entire belt for missing teeth, replace as necessary.
The next thing I would check would be the flywheel under the antenna. Check it for any signs of corrosion around the bearing. Remove the drive belt and slowly rotate the antenna see if you can detect any friction anywhere is you rotate the antenna. You could try a spray lubricant (like WD-40) but be careful of overspray, keep it off any electronics!
The next thing I would check would be corrosion on any power connections (all the way back to the main power and the fuse. Corrosion on any of the connections will lessen the current flow and make the drive motor weaker. Sometimes corrosion and salt can be cleaned off with a “contact cleaner” (or alcohol in a pinch) but if there is heavy damage you might have to replace the connectors completely. Be sure to remove all power before disconnection and connectors and be sure that they are dry before reapplying power.
Lastly (and most expensively) you might need a new motor.
If you operate in saltwater, corrosion on the connections would be my guess for the cause but I still would check these in order, from easy fix, to the expensive fix.
When you replace the dome be sure the O-ring gasket is in good condition and well lubricated with silicon grease before you close the unit. Replace the O-ring if you see (or feel) and nicks or compressions in the rubber. Take care that there are no twists in the O-ring when you reinstall it.

SOURCE: furuno 1621 radar will not power up

With a voltmeter, verify that you are getting 12V at the plug end of the power cable. If so, check the fuses (there should be one or two fuse holders on the back). If all of that fails you will need to send it in to Furuno for repair.

SOURCE: Furuno 1622 doesn't work, water coming out cable at screen!

yes the cable should be replaced if you are lucky, the unit is still OK (display) Try the new cable, draped across the boat before rigging. If fault exists with new cable, replace system, or find a new display on ebay

Have a furuno fr240 mark 2 and rafar image return only when changing range. also when given time image slowly returns but later radar dies. what problem can it be?


Of course this could be many things, but it sounds like your auto clutter < labeled by Furuno as AC Sea Auto, is on and out of adjustment. Try turning off auto sea clutter and manually declutter the screen, should help, otherwise, 847-746-0100 will definately help you.

Do not get any images on the radar screen


depending on which radar it is, it may be the video coax inside the radar cable. Otherwise possibly your magnetron or mic. Try calling mid-shore electronics @ 410-228-7335 they may be able to assist you.

No radar target images


Sounds like your video cable inside your radar cable. Also brings your Gain back to zero, STC back to Zero and rain back to zero. Next increase your gain until you see a picture. If none of that is working, check your cable then finally call a dealer.

Hi, I have a Radar Screen. Furuno 1942 MK2 . What Radar Dome can i plug this into. I have a Furuno 1720 Dome


A 1942 is a 6 kw radar a 1720 is either a 1.5 or 2.2 kw dome. The two will not work together. Besides the cabling is different. Also the radar cable on a 1942 is round where as the 1720 is square. The 1942 display should work fine on a 1943 navnet radar.

Radar Displays the image upside down


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 Radar 1623 and 1715


Hello.

According to the operating manuals of the two radars (found on Furuno's Website (www.furunousa.com), they do use the same antenna cable.

Hope this was helpful.
