![]() I recently bought and installed a Lowrance Elite 4-M GPS. It works great and I'm pleased with it. Just last week my old VHF sorta crapped out so I bought a new Lowrance Link-5 VHF. Now, the Link-5 can display GPS location, time, cog, sog and local time but it needs to be connected to a GPS via its own NMEA cable that came with the VHF. Well, I ordered the optional NMEA cable for my Elite 4-M GPS so I could connect the two. First off, there were NO instructions as to how to connect the colored wires of each cable. I had to look up any and all information I could find on the Internet. The NMEA cable from the VHF was labeled with little tags that identified the data in (+) and the data in (-) wires. The data in positive is yellow and the data in negative is green. I found out on the Internet that the data out (+) wire on the NMEA cable from the GPS is yellow while the data out (-) is green. So I connected them properly and the VHF displayed *no GPS information*. Huh? I couldn't figure out what was going on as it should have worked.I even checked the data out wires using a volt meter and noted a pulsed signal about once every two seconds that was around 3.5 volts so I knew the GPS NMEA was working. I noticed a bulge in the GPS NMEA cable so I stripped off the insulation and, lo and behold, there were a couple of diodes hidden in there, I suppose to keep damage from being done should some dumbass hook the wires up backwards. The diode on the yellow wire was soldered in backwards so I bypassed it by soldering the yellow wire from the VHF on the other side of the diode and the two units linked right up and the VHF now displays the Lat/Lon, etc. This is good for any potential distress call as it will include my position whereas prior to the connection I would have had to manually input the lat/lon prior to making a distress call. I haven't activated the DSC side of the VHF because I'd have to get some dumb MMSI number from the government first and it looks like a bunch of stupid forms to fill out and I'd have to buy an operators license because I go out of the country from time to time. **** that! So, what should have been a twenty minute connection took all afternoon. Now, I know why Capt. Skippy never goes sailing anymore. With all the crap he has on his boat it must be a full-time job keeping them operating. -- Sir Gregory |

That's all well and good until one notes a diode installed backwards (black line facing input of data) so no current can pass that way. Made in Mexico - no wonder it was defective. -- Sir Gregory |

I notice the Mexicans working at the fast food dispensaries can make change and count better than the products of our union school teachers. |

Diodes only pass electricity in one direction. If they are installed in the circuit backwards they stop the current from flowing. |

Diodes only pass electricity in one direction. If they are installed in the circuit backwards they stop the current from flowing. But, as Wayne suggested, if you reverse the diode's connection they should, if originally installed backward, allow current flow. If not than (1) there is something else wrong, or (2) the diode is faulty. -- Cheers, Bruce in Bangkok |

If there is a diode on the positive wire and it's installed backwards then any positive current *sees* no circuit. If one were to hook the negative wire to the positive wire, current might flow but the radio wouldn't know what to do with it. It might even damage the radio. You and Wayne are so stupid you seem to think an NMEA circuit is like a light bulb in that it works either way. Duh! They probably put the diode in the circuit in the first place to keep stupid people from hooking the wires up wrong and you and Wayne say go ahead and hook up the wires wrong and it'll probably work. ROFLMAO!!! Now I see why you had to abort your circumnavigation less than halfway around. -- Sir Gregory |

You and Wayne are so stupid you seem to think an NMEA circuit is like a light bulb in that it works either way. Duh! Are you being deliberately obtuse? Or are you just stupid? If you connect a diode in series with a DC circuit, in either the positive or the negative leg, current will flow through the diode if it is connected correctly. If current does not flow then reverse the connections to the diode. No one was talking about connecting the positive leg to the negative leg of the circuit. Actually, a very slightly competent electrician would simply take his handy dandy multi meter and check the resistance of the diode and reverse the meter leads and check the resistance again which would tell him whether the diode was connected properly, or not. It would also tell him whether the diode was serviceable, or not. Since you can't seem to handle this technical task all by your self certainly does tell us something about your electrical knowledge. They probably put the diode in the circuit in the first place to keep stupid people from hooking the wires up wrong and you and Wayne say go ahead and hook up the wires wrong and it'll probably work.
