Default Furuno 21X Radar Problems...

Similar to the previous thread, only mine is a 21X CRT unit. Array sweeps twice, then stops and I get an error message on the display stating "zero heading - pulse error." Unit is older, and I'd like to get one more year out of it before updating all the electronics. Any ideas???

have someone spin the array by hand a few times (like 6-10 revolutions), while it is showing the message, does the message go away while you are spinning it?

Furuno or Raymarine?

In any case, I think the issue is that you are not getting the 'heading pulse' with is often a simple repair, but not one for a DIYer. Check with an authorised Dealer/service center. If it is a 21x (not 21xx) you are really overdue for a new radar...
