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

Gain set too low?

While tuning set BRG signal is missing is been displayed

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.

yes, this is available from Furuno give me an email address and we will quote can drop ship to marine operation or 10 days delivery John Barry 847-746-0100 [email protected]

To be check the Fuses:1)for antenna ,2)for modulator unit
that are from 4amps until 7amps slow blow

do you still have this radar dome? i am looking to replace the one I just busted as I didnt have enough clearance on the barn door. my email is [email protected]

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

You either have a bad m.i.c., magnetron or if board. Without any other info it's hard to say. More than likely this will be a costly repair.

The gain truned up and filling the screen with dots tells me the M.I.C. is Ok. Since you array fills with water, there is a very very good chance that the wave guide has given up. A good tell tale sign is that there is white powder laying on rectangular aperture located in the center when you raise the lid on the chassis. A new Array will probably be needed and that will cost you anywhere from $800.00 to 1200.00 just for the part. The water is probably getting in from the array from a bad install as well. normally the chasiss does not leak unless you did something wrong.

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
