T1 ATU problem?

I have been hooking up a G5RV Lite & I am hooking up the antenna twin lead
balanced line to an elecraft wideband HF balun I built which then connects
to a little Opek SWR meter & then to the T1 which connects to the radio,
either a K1 or an FT817ND. (Described in reverse direction.)



At first, I had a problem with a short coax connector that was not
conducting due to a broken PL259 connector so I removed that & converted it
to have two lugs to connect the balun to the end of the antenna feed line's
SO239.  When I put it all together at home & started testing conductivity &
ruling out any shorts or breaks, I noticed conductivity between the shields
& the center feed.  I finally isolated it to the T1 & wherever I test the
outer to the inner leads of the BNC connectors, there is no resistance &
they all conduct.  Something is wrong with this recently purchased
pre-built unit, wouldn't you agree?



I just want to be sure about this before I call &/or send it back for some
repair so I thought I would check to see what anyone thinks or might
suggest.



I don't think there is anything that I could have done to cause this but
one never knows, I guess.  Could I have done something to create a short in
the tuner by hooking it up improperly at one time or another, possibly?  I
would hate to think that these instruments are that 'fragile' but then
again I am not that experienced, yet, being a ‘rookie’.



Any suggestions or comments are welcome.



Thank you,
