I own a JRC 1000 radar on a 31' sailboat. It was working trouble free for years. Last summer, it started shutting off while operating. What can I do to fix it?

Question edited for clarity.
Question moved from Office Equipment category to JRC Radar.

The pulse generator is in the dome. Check all the connectors for corrosion. Help in the link and it is a common error. It sounds like you need a new 'professional'.

Buy a new one. If it did, it probably fried the controll chips.

After black out of ship during audit Radar Model JMA 9303 no work.
Radar start work and after 15 sec. switch off.
Radar not show target and display error "ANTCLK ER" ( Bearing pulses are not
sent to the display unit)and "TRIG ERR" unknown error.
Antena of radar working.

Any body can suggest the solution

As you look at the back of the display unit, the power plug has 7 connection posts.
Top left is pin 1 Bottom Right is pin 7
Pin 1 ..... + 12v
Pin 2 ..... - 12v
Pin 7 ..... Boat Ground

Hi does any one have a scanner for a jrc1000 they would sell me please can not find one for sale anywhere.

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.

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)

Thanks!

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.

found my fault not i the power cable in, but the interconnect to radar dome..approx 50mm from radar screen a break in the wire, found it just by wiggling the cable.. the set wont power up if the interconnect not connected or is faulty
