A furuno 1715 lcd radar was wired to battery backwords

Trace power wire from unit to find in-line fuse. check fuse. If OK continue to battery or power panel using 12 v dc meter. must have long ground wire to battery ground(-) to meter(-)

You can interface the GP30 to the 1715 and get Lat/Lon readings where the cursor is. The GPS has extra wires in the power cable. The 1715 will require a NMEA cable pn 000-154-028. Connect the white GPS wire to the yellow radar wire and the blue GPS wire to the green radar wire.

Cek wiring to scanner, change reedswice sensor /heading sensor. If the problem not solve, change the display with the new one.

Here you go Sir,

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.

Yes and it is in the book a new installation needs calibration!! The rough tuning is off by the sounds of it

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.

i have a furuno 1700 radar ,when i switch it on it goes to stand by ,when i press the standby button you can see it scanning but no land appears cheers alan

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.
