Mark, both of my PL cables work just fine.. and I've checked with my meter the connections of the tips (where the tip of the cable actually touches it) and
between the solder joints of the jack to the switch, and from the switch to the other jack, and form jack to jack, and in all these three my meter beeped (it shows there is continuity..)
I want to mention although, that I wasn't sure which solder joint is which, so I touched with one tip of the meter the inside of the jack (the sleeve), and with the other I tried to find out which solder joint is the one connected to it, and then when it beeped I knew it should be connected to Ground.
I've done the same process with the Tip and Ring...
Is that okay?? (If not, then I guess I did
mis-wired the jacks..
