Les,
  I can only reply to the reversed polarity gene that I've inherited from some 
distant relative.  I'm a pretty technical guy, But, on occasion, I've managed 
to 
screw up some equipment. 

Reverse happens,
Good luck!

Subject: [Flexradio] Reverse Polarity Flex 1500

I loaned out my Flex 1500 along with a 222 transverter to a friend who wanted 
to 
experiment with the set up at his home for a few days. He called me and said 
that he couldn't get the unit to work, and asked if I would take a look. I went 
over after work expecting to find the usual assortment of software related 
issues.

Instead, when I was looking over his connections, I happened to touch the USB 
connector on the front of the unit. It was hot to the touch, and I immediately 
realized something was amiss. We unplugged
everything, and that's when I spotted his error. I had provided a small 
switching 13 volt power supply equipped with Anderson PowerPoles. He was 
unfamiliar with them, and didn't realize that they were reversed in alignment. 
When he couldn’t get red to mate with red (physically) he instead mated red to 
black. The result was that he applied reverse polarity to the Flex 1500 for 
quite some time.

The unit now refuses to power up (no power indication on the front panel LED 
switch) and otherwise function.

So, how screwed am I? And no, this isn't one of those "I have a friend" 
stories, 
when the friend is me. Callsigns have simply been changed to protect the 
innocent.

73,
