So I have a 4 way switch circuit that is giving me some problems. I have included a diagram attached. What is really weird is that the first light is not coming on at all, and the 2nd light is functioning exactly the way I would expect a 4 way switch circuir to work. Anyone have any ideas?

I thought maybe it was a bad wire in the fixture but it test OK on both a continuity test w/ my multimeter and when hardwired into the circuit by-passing all the switches. I don't see how it can be that the lower light is functioning w/out the first light working, given that the hot feed passes through the first light.

TRY this:

Unscrew the bulbs in the first light .... does that make the 2nd one quit?

the feed from the panel needs to go directly to the first 3 way switch. the black from the first light has to connect to the black from the second light or to the same wire at the second 3 way. with the wires you have now you can't do it properly. if you tie the 2 blacks together at the first light the second light will work fine. in your drawing the first light has no neutral connected to it.

Not sure if you have access, but the easiest solution would be to run a new 2 conductor cable from light to light....
This is useally a best answer to deal with multi switch/ luminaires locations.

Merci,
