Yes, yes, and yes...

Your grounds are probably poor, and the voltage is finding its way home
through the other wires.  Strangely enough, the unused wires (eg Hi when
you're on Lo) are grounded.  When you do the relays you will probably
set up a nice solid ground point and render your problem moot.
