The important indicator
to remember is that the
positive, hot wire has the
in-line fuse. The negative
wire does not. So, when
you’re hooking up the
external power cable, only
pay attention to where the
in-line fuse is and not
what color the collars are.

Dear Sergeant Atkins,
For such a small item, that external power cable has received a lot of
attention. There are several versions of this cable that the stock number brings.
Some have this problem, some don’t. Thanks for the update.

PLGR…
Dear Half-Mast,
Using the external power cable,
great way to tap vehicle power
and avoid the use of batteries to
operate your AN/PSN-11 preci-
sion lightweight GPS receiver
(PLGR).
But there is an identification
problem with the two leads of the
power cable. Neither of the leads
is marked. There is no positive (+)
or
negative
(-)
indication.
However, one lead does have a
white collar next to the spade
connector and the other has a
red one. But guess what? The
red one is the negative or ground
wire. The white one is the positive
or hot wire. This is contrary to
what most people would think.
looks like
another plgr
power cable
was hooked
up wrong.
yeah, the
color of the
connector
collars can
fool you.
