I have just bought a SeaRanger 5600 on Ebay and apparently it has a manual and I would be happy to exchange scans, pdf's or photocopies. Your postings are the most information I have found on SeaRanger so far. I scored a SR5561 with no paperwork or accessories at all. My only concern is hooking up the 4 pin power plug. It is just like a hard drive/ CD rom plug in a computer. My bet is the 5600 has the same plug. I just do not want to fry it. If someone would not mind telling me or sending a scan maybe I could do something in return. Thanks much.
I also inherited a SR5561 with no paperwork and am concerned about the 4-pin hook-up. I can pretty much figure that the larger red and black wires are positive and negative from the battery. But what about the other two smaller wires? Can you give me any advice? Thanks.
I have the above listed Loran C with stripped coupler threads - I have tapped the coupler and run a die on the antenna, but they've just been abused too long.
I can get a new antenna. How to fix the coupler? Helicoils are too expensive and I don't think there's enough wall to tap larger. Other thread repair materials are cheaper but for stainless I need more metal than I have.
Also, don't have manual.
And... the power cable is sketchy - not sure if the unit reboots itself as a result of normal operation or because of a bad connection - considering replacing power connector with something more commercially available.
Finally... there's another port on the back - what is it, NMEA 0180 out?
Ken---you might go to Auto Zone or some other auto supply places and get a helicoil that will fit those threads. Seems like I vaguely recall you'll need to drill the threads out, maybe. At any rate, the helicoil is the way to go for your problem.
