New install.

box 1 : Line, traveller white, traveller red

box 2 : load, neutral, traveller white, traveller red

I have to use one traveller to transfer Line or neutral to one box so I can install the main switch.  It leaves me with just one traveller left.  No matter what, I always get the blink red.

the only way I got to setup the switch, is by connecting the second traveller screws on both switches to a neutral line.  But then, I get no light on the load...

Help please... I cannot run another cable between box.

Can it work with just one traveller ?  Do I need to jump some screws or câble ?

thx
