I have a Furuno 1715 and the array slows and stops frequently.

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.

Here you go Sir,

Adjust the motor mounting so belt don't slide up and down including the tension. Check the cabling connections, axial position sensor and rotor for weather damage. if problem resolved seal the housing with a silicon gel. If belt has visual wear 80% chance thats your culprit. Please be very careful for the magnetron has very HIGH VOLTAGE.

Heading pulse is a reed switch sensor built inside the dome. upon each rotation of the array the reed switch is activated. Do a visual inspection of your array (inside) to make sure it is spinning (verify from a distance). Don't get eye level with the rotating array it can cause great harm to your eyes. Normally I have seen the belt slip off and also the lanyard attachment get caught in the array. Check those two things as well.

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

internal damage to the display, fixable by Furuno, and probably economically feasible (guess $250 with round trip to Furuno)

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.

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.

you can connect them by NMEA, but synchronize, no.
