Some cable test stuff
Remove the cable from the display, leave the dome connected
I thought the cable end had pin numbers but let me know if it doesn't,
the video pins are 1 and 2 which are located
either side of the key slot
Video pins 1 & 2 resistance 46 Kohms colors 1 white signal, 2
black return
Azimuth 12 &13 resistance 10 Kohms colors 12 purple azimuth +
, 13 grey azimuth -
Trigger 4 & 7 resistance 10 Kohms colors 4 orange trigger
+ ,7 yellow trigger -
Data I/O 6 & 10 resistance 160 Kohms colors 6 green data + , 10
blue data -
Approx. +/- 5 ohms tolerance.
Below is a pin chart of the display connector
key
2 1
5 4 3
8 7 6
11 10 9
13 12
Other pins on display connector
Battery - pins 3 & 5 both black
Battery + pins 9 & 11 both red
Shield pin 8
Dome connections
Video pin 8 white
Video rtn pin 7 black
Trigger + pin 6 orange
Trigger - pin 5 yellow
Data + pin 4 green
Data- pin 3 blue
Azimuth+ pin 2 purple
Azimuth - pin 1 grey
Battery + red
red
Battery - Black
Black
There was a note that some cables only have one set of battery
connections pins 5 & 9
Battery connections on 3 & 11 not present on all cables. You should
have the doubled power wires with the 4KW unit.
If the test results did not have the correct ohms then they said to
check it at the dome
If the dome checked ok, then the cable was bad, and to continuity check
the cable to confirm
a bad cable

JRC 1000 MKII bearing pulse error on receiver screen. Connections to scanner good and scanner turning. How can I determine if the problem is in the receiver? How can I fix it? louonboard

Normally the bearing pulse comes from the bearing pulse generator built inside the motor. Every time the motor turns it sends a pulse down the line showing the radar that it is indeed spinning. There is also a Heading pulse that comes from an electric eye elsewhere in the housing. The other thing could be that the wire carrying the bearing pulse is not getting back to the display. More so than often, it's the motor. I would have the display sent out to be checked on a simulator if there is a marine electronicshop nearby.

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.

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.

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 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

Furuno 1623 Radar reading "no heading pulse"

The messages “NO HEADING PULSE” and “NO BEARING PULSE” means that the display is not communicating with the scanner (antenna). Both of these signals are generated in the scanner if you get this error check that the antenna cable is firmly connected and that the contacts are clean and corrosion free.

If the connection at the display looks good and feels like it’s properly connected, check the cable for any damage If you find damage you could try to repair the wires BUT (because of corrosion and moisture problems) IT IS STRONGLY REMENDED that the cable be replaced, but it’s kind of expensive $275.00.

The Part number is 000-130-034. Depending on the marine shops in your area they may have it in stock (or they can order one) but you can get it directly from Furuno at;

I hope it’s just a loose connection. Good luck!
