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.

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.

ROFLMAO!!! Now I see why you had to abort
your circumnavigation less than halfway
around.
