We have a Furuno 1623 radar. We had the mast down and after putting it back up had some trouble with the radar cable getting stuck on its way back up on the messenger line. We got it up to the dome but it had a hard ride. We plugged it back in and the screen has all the normal view on the screen but the return image. We were sure it was the wires near the plug at the dome so got a 9 pin connector and some pins for the repair. Back up the mast we checked the 9 pin connector and all showed good connection back to the screen end of the cable on the ohm meter except #6 the video wire which showed a break.
We cut the blue #6 wire back bit by bit to where the inner wire separates from the outer wire of the coax where we found the break at the solder connection of the inner #6 wire. At that point we found connection with about 4 ohms showing. All the other wires were between .8 and 1.2 ohms on our budget multimeter so are wondering if 4 ohms might be normal for the skinny video wire.
If that is not a bad sign our plan is to use a tiny crimp fitting we got along with the pins to a replacement wire with a pin on the end. Then we will cover it and a bit of the dialectric with electricians tape and/or heat shrink, depending to isolate it from the outer wire. Soldering being pretty tricky at the location. We have not dealt with video wire before, so does this seem a reasonable plan? Thoughts? We are also wondering what the 2C-2V noted for the coax in the manual means. Sorry I was long winded.
Thanks.
