kinda burnt out this week. i have a four way circuit that has probly never worked. after checking all the switches making drawings till i cant see straight, all i know for sure is the problem is at one end. what configuration would take the 4way out of the loop? there should be power to one terminal or the other at all times right?

Two terminals should always have power. Which two depends on how the upstream 3-way is set and how the 4-way is wired internally.

Should have power at each switch, and power to one of the travellers too.

If it never worked ... I'd check how the traveller's are connected

Slap me if it's dumb but could any type of cali switch wiring be involved to add to the confusion/exhaustion?

Could be back fed. Sending power down on the white and some one confused it with a neutral. Pull the fixture down and see if the travelers go through the light box.

Funny this thread showed now as i just came back from fixing a neighbours
4 way. It had me confused for a while cause I'm used to seeing 4 switch 4
ways wired power-3way-4way-4way-3way-light. This was wired with both
the power and light out of the first 3way box. Combine that with wires removed
from various places by the homeowner trying to figure it out himself, and it took
a while to sort it out.
Since that likely doesn't help the op, I'll throw out a couple thoughts:
1)Identify where power enters the switch system
2)Identify where power leaves the switch system to go to the light
3)If you have to, un-wire the boxes and use your meter to find both ends
of each wire. Make a drawing and put it back together properly.
Was this post useful or'd I have 1 too many beers?

Beer makes everything better.....:thumbup:

Remember all the configurations we had to do back in our apprenticeship Plugs?:whistling2:

power-3way-4way-4way-3way-light.

3way-4way-power-light.-4way-3way.

light-power-3way-4way-4way-3way.

etc etc......~CS~

Meter out your 4 ways to determine which way the = and X are going. I can't remember the details now but I had one job with weird 4 ways.

There's no standard. Some (like Levition, I think) go side-to-side. Others (P&S) are end-to-end.

Yeah, like I say, I can't remember the details but there was something weird going on that day and the only thing that solved it for me was ohming out the switches.
