Raymarine raytheon 4Kw Radome array question
In article ,
says...
I've got a unit that is about 7 years old.
Recently, it started turning erratically, causing the display to
pop the Antenna not rotating message, and shutting off.
The antenna's turning, but slows about every 1 to 1.5 revolutions.
I've changed the belt, and had a good look at the unit. It appears
clean, and uncorroded.
I'd like to suspect the stepper motor, as that would be a pretty cheap
fix, but before I go there, I'd like to hear some opinions of what
else might
be causing the stepper to speed up and slow down like that.
TIA
I would highly recommend calling Raymarine and talking about this with
one of their techs.
A couple of years ago I had a bad mosfet chip on my scanner pcb and they
helped me diagnose it, isolate it and point me in the right direction
for a $4 part that fixed it.
If you get someone whose not so helpful, call back another time and try
again.
