GFCI Receptacle Help
Hi All,
I just became the electrician of a theatre and was asked to fix something I'm unfamiliar with.
We have an old GFCI outlet in a grassy area off of a patio and this provides the only light to the area. It's not working, and I'm not sure how to approach fixing it. It comes off of a working circuit on the patio, where all of the lights are functioning. As far as I can tell, it just goes from the patio straight out to the GFCI and back.
I used a voltage tester to check that power is getting to the receptacle, and indeed it is. I inserted the end into the outlet and it told me that power was getting there as well. But when I put a test light in, I get nothing. Does this mean that the neutral is faulting somewhere after this GFCI and before getting back to the rest of the circuit?
Honestly, I don't know much about GFCIs either...
Any help would be appreciated! Thanks!

You need to first look for another GFCI feeding that one. Then test for voltage using your test light or better an analog multimeter between
- Black (hot) to White on the line side.
- Black to ground on the line side.
- White to ground on the line side.

Hi Ray,
I don't see any other GFCis on the line.
Also, you specified an analog multimeter. Is there a reason a digital one won't work?
i hear what you are saying about getting a professional electrician in here, and I wish that was an option at this point. Part of the problem with working in theatre is that there is no money, so they hire someone like me who knows about theatre electricity in lighting, and hope that I can learn enough about the rest to help out when it's needed.
If I get desperate, I might be able to get the money for it from the company, but it's unlikely at this point. So anything I can do will be beneficial.
Thanks for your suggestions and help!

A quality digital multimeter (like a Fluke) would be fine but the cheap ones should not be used, analog is better in that case.

A cheap analog multimeter is less affected by induced, ghost, voltages then most cheap digitals.
Often they are hidden behind boxes, furniture, or other things. They could be inside or outside or almost anywhere. If you just don't see one take the voltage reading I suggested and we will go from there.

I tested the voltage at the junction before the pipe goes into the ground and back up fifty feet away, and was getting between 115 and 125 volts.
I also checked where the pipe comes up and saw that where I had pushed dirt away had be replaced from below and that the pipe was slightly damaged. My guess at this point is that a gopher or another underground animal hit a weak part of the pipe and damaged it enough to affect the wiring? Is that feasible? I think I'm going to do some digging and take a look at that joint.
