Question about Furuno 1715 LCD Radar System GPS Receiver
I was getting an inconsistent image on the monitor so I took the cover off the radar dome. The antena did not spin until I messed with it. Unfortunately, wile underway this is not a possibility. Any suggestions?
This is a belt driven antenna. That would be the first thing to check, to be sure it’s not slipping. This should be easy to see if the motor is spinning but not the antenna that would be the problem.
I don’t recall if this model uses a “toothed belt” or not, but if it does check the entire belt for missing teeth, replace as necessary.
The next thing I would check would be the flywheel under the antenna. Check it for any signs of corrosion around the bearing. Remove the drive belt and slowly rotate the antenna see if you can detect any friction anywhere is you rotate the antenna. You could try a spray lubricant (like WD-40) but be careful of overspray, keep it off any electronics!
The next thing I would check would be corrosion on any power connections (all the way back to the main power and the fuse. Corrosion on any of the connections will lessen the current flow and make the drive motor weaker. Sometimes corrosion and salt can be cleaned off with a “contact cleaner” (or alcohol in a pinch) but if there is heavy damage you might have to replace the connectors completely. Be sure to remove all power before disconnection and connectors and be sure that they are dry before reapplying power.
Lastly (and most expensively) you might need a new motor.
If you operate in saltwater, corrosion on the connections would be my guess for the cause but I still would check these in order, from easy fix, to the expensive fix.
When you replace the dome be sure the O-ring gasket is in good condition and well lubricated with silicon grease before you close the unit. Replace the O-ring if you see (or feel) and nicks or compressions in the rubber. Take care that there are no twists in the O-ring when you reinstall it.
