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.

I wish you'd shut up as you're obviously stupid.

On a two-wire DC circuit there is a positive
wire and a negative wire. 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!

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.

That's not what Wayne said. He said, and I quote, "I suspect that if
you had reversed the two wires that it would have worked fine."

Reversing the *two wires* means connecting negative to positive.

And you agreed with that little bit of folly.

Sorry, your ignorance seems to be showing again. Most diodes have two
connections, sometimes labeled Cathode and Anode, and sometimes marked
"+" and "-". To "Reverse the connecting to the diode one would connect
the wire originally connected to the Cathode to the Anode and
vise-versa.

It's not my ignorance that's on display but rather your lack of
reading comprehension. You jumped to the conclusion that Wayne
said to reverse the diode when he said to reverse the WIRES from
the GPS to the VHF. Now, you're trying to weasel your way out
of being caught being stupid. Sorry, but nobody's buying it, dude.

Now, even a nephrite electrician would be able to figure that out so
apparently your electrical knowledge is extremely limited, or you are
just trying to be an asshole.

You are the one giving asshole lessons. Wayne's newest claim that
NMEA 0183 doesn't differentiate between positive and negative only
shows a great deal of naivety. He seems to think there's only some
kind of loop where it doesn't matter if the current runs one way
or the other. How droll! He's got DC mixed up with AC apparently.
