There is an internal Heading magnetic or optic switch which terminated with a think cable and wellow plug on the T/R PCB.
Check that conduct by a multimeter,fitted in place and try again
on display unit for targets stabilizing.Maybe also using that RDR
a resolver motor counder,you also check tha cabling of this.
For more info mast be read the Radar's manual. I am JRC spcialist, no Furuno but I have RDR experience.

It cannot determine a heading, have you also damaged an internal antenna or positioning / gps device inside it? It is unsure which direction it is pointing in but uses triangulation to determine this.

That requires either an electronic compass unit, or gps to achieve correct heading and hence correct orientation of the radar image

Make sure the antenna/scanner is turning in tx mode. The bearing signal is generated inside the scanner drive motor. This problem usually requires replacing the motor.

How to install FURUNO magnetron MG5436 for Radar


Assuming you have the right magnetron for the right model radar, you desolder the two leads, remove the 4 or 6 mounting screws and reverse the process for the new maggie. Let radar run in standby for 30 minutes before going to transmit. Most Furuno radars have auto-tune and will tune itself to new magnetron.

Brg sig missing


That usually means the antenna is not rotating. Verify that first then check for physical obstructions. More than likely it's a defective motor assembly.

Furuno MK 1942. The antenna does not spin. There is a message on the screen "HDG SIG MISSING". Though the magnetron is fairly new one. I can´t access the Instalation Setup at MENU > OTHER...


Either you have a bad cable, or the motor has given up. Sometimes it can be the mod. board but the bearing pulse generator is located on the motor itself. Also check to see if theres a switch on the back.

The top half of the dome blew off while towing boat. Any way to replace the top half with a used or new piece? Don't need to replace the whole dome.


As long as no damage was done to the enclosure from the lid blowing off, there is no reason that you can't simply put a dome on it. Try contacting furuno direct to see if the part is available. Make sure you know exactly what model radar you have before you call.

Error SB SIG MISS on FURUNO CRT radar?


Either your reed switch is bad or your antenna is not rotating. You may hear the motor spinning but that does not mean the array is. If the array is not spinning make sure the belt did not come off the motor. Start there.
