Hello there,

I also need this very same power cable. Did you find one already? maybe you can tell me wich one of the 7 input connections is the + and - DC power connection so I can connect this thing myself with a home made power cable. Greetings. Stan (holland)

This is a bearing pulse error. Either the bearing pulse generator inside the motor is bad (Replace the motor) or it's in the radar cable or display.

Normally the bearing pulse comes from the bearing pulse generator built inside the motor. Every time the motor turns it sends a pulse down the line showing the radar that it is indeed spinning. There is also a Heading pulse that comes from an electric eye elsewhere in the housing. The other thing could be that the wire carrying the bearing pulse is not getting back to the display. More so than often, it's the motor. I would have the display sent out to be checked on a simulator if there is a marine electronicshop nearby.
