Top left is pin 1 Bottom Right is pin 7
Pin 1 ..... + 12v
Pin 2 ..... - 12v
Pin 7 ..... Boat Ground

After nearly 4 years I dunno if you got this sorted.
The question is ambiguous, as Raymarine radar comes with wiring harnesses; the display end is a plug-and-play 12-pin male to the harness end female; the other end goes up the mast in a plastic sleeve to prevent damage to the 8-pin connector and the 2 or 4 power cables (depends on "light" or "heavy").
There's a means of connecting a digital radar to the C120 but I don't have that so don't know the specifics.
Is this the sort of information you were looking for?
Trace power wire from unit to find in-line fuse. check fuse. If OK continue to battery or power panel using 12 v dc meter. must have long ground wire to battery ground(-) to meter(-)
Most automotive electronics work on a 12 Volt DC system. You must be using adapter capable of providing about 12 to 14 volts because car batteries provide 12 volts; but car alternators put out 13.8 volts. Do not attempt to connect to an adapter that put out AC voltage!
Those are no longer serviced or have parts available. This unit did use a standard style flat 2 pin connector that you maybe able to find in some electronic parts store.
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) [email protected]
Thanks!
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
