KX3 Power Cord

Which wire is the positive on the cable the one with the long striped lines?
or the other which I think is the negitive. Looked on line and in the boob
can't find.

Fred,

I never can remember, but my ohmmeter will tell me in an instant. Stick
one probe in the center conductor and check each lead for continuity -
the one with continuity is the positive lead.

Fred, It -is- in the manual, on page 4, under POWER SUPPLY:

"A power cable with a 2.1-mm plug is supplied. The
wire with the white stripe is positive. Trim the cable
to the desired length. Plug the cable into the 9-15
VDC jack, shown at left in the illustration below."

But, as Don says, when in doubt, your ohmmeter will reveal reality.

Don, better use a Voltmeter, not an Ohmmeter ;-)

How do I use a voltmeter to check continuity on a power cord connected
to nothing other than the meter?

It's always a good idea to double check with a meter. It's not
inconceivable that the power cord might later on get mixed up with
similar type cords... which might use a different color coding
system. If in doubt...... measure.
