Measuring voltage between ground and rod

I was hooking up a grounding rod to my trailer.
I got a small zap.

I checked again and it only happened if a small cut on my hand touched it. If anyone has ever played with 9v batteries you know the same is true for them also, if you touch it to a cut you get the same type of zap.

I measured it and it is reading about 7.5v, dont know what amp.
I checked and most of it seems to be from a monitor. I unplug the monitor and it drops to 2v.

Is it normal to have a small amount of voltage running like that when things are plugged in?

Describe this setup further.

Why are you hooking up a ground rod to a trailer? What is the entire setup?

In most areas you need two ground rods six feet apart.

As for the tingle, I have this spot on my had that when the end of something like a wire touches it, it feels just like an electrical tingle. I think it has to do with the nerve endings.

To be safe, turn off power, at the main to the trailer stansioin while hooking up the ground rod.

Make sure that you have the ground and neutral properly bonded at the main disconnect.
