Electrical question

[woodstock]

Use a bigger hammer.

Likely the connections are bad, at no load the volts look good, under a load they drop right off. have a qualified electrician check the receptacle

It's in a small wooden utility building and I traced the line back to the house and it comes off the outlet required underneath the house. It's got to be that outlet. I'll change it out and see what happens...thanks.
