So I have a problem.

I bought a boat with a LMS 332c with blue connectors and the GPS module is not responding. I have done a ton of research and I am beginning to think that I may be overlooking something or the Lowrance Tech Support guy is an idiot.

I am getting 12 volts to the module. That doesn't seem to be the issue. So I call and talk to Lowrance or whoever they go under and told the guy my issue.

He told me that I needed to get a Female 60 ohm terminator. I told the guy that it is the female end and you can put 2 females together (at least not on the blue prong)  ;D

But he insisted that was what I needed and I ordered it.

So I get the 60 ohm terminator in today and discover that they won't go together. Hmmm. > He must have thought I had the Y-adapter cable or the soft T. I really don't know...

So now I have the 60 ohm terminator that doesn't fit and a GPS module that still won't respond.

I have a single wire that runs from the head unit to the "hard" T. The LGS-2000 is connected to the "hard" T. Then I have a female plug with nothing connected to it. From the research that I have done it seems that I have not completed the network.

If anyone has any info please let me know. This is very frustrating.

Thanks.

Of course, as you point out, you need a male 60 ohm terminator to properly complete the network.  This makes the network communicate most efficiently, but I doubt the lack of this component is the cause of the module not responding.  Don't get me wrong, go ahead and get the male terminator to complete it.

Modules not responding could essentially be any component in the setup.  The first check is NMEA 2000 power (or antenna power).  I am assuming you have verified good voltage to antenna with voltmeter.  Without NMEA power your antenna will not function.  Unplug all your network connections from the antenna to the unit and plug back in.  Sometimes moisture causes an intermittent connection.  I recommend coating all network connections with dielectric grease to foolproof them.  You can get this grease at NAPA and other auto stores.  If these steps don't fix it, could be a bad antenna.  Find a buddy with an antenna you can swap to see if this is it.  If this swap doesn't fix it, then your problem likely is a bad network tee or cable.  Worst case it's the unit, but that happens in less than 5% of these specific "module not responding" problems. 

I called Lowrance back today and spoke to someone else. He seemed to have more knowledge than the last guy.

I am going to find someone local that has the blue connectors and test the antenna to make sure that it is not my primary issue.

If it works then I am going to see if I can locate a male 60 ohm terminator. Lowrance doesn't produce them anymore.

If I can't find one the guy said I can buy a kit and make the connection work for about $50.

We shall see.

If anyone lives in the Arlington, TN area and has the blue connectors let me know. I need to test my LGC-2000.
