Getting Zapped

[fencer]

Recently I have experienced stray voltage problems. So I looked around for info on ground fault probes. A good idea ( some don't even recommend them) I installed a DIY one and poof no shocks. But a troubling aspect of this it doesn't fix the offending problem. So tjis is what I want to do
1. use a multimeter one tip in the water and the other in the grounding slot of a plug
2. set for AC and systemactically unplug things

Is this correct way or is there a better way
