Presumably when larger loads are put on it, the voltage drops.
So, get a heater or similar, and plug it in. Then start measuring
voltages from hot to neutral, tracing back. At the heater it will
be well below 120V. Someplace up the chain it will be 120V, normal.
Then between the two, apparently something is wrong with the neutral.
The neutral current is in a conductor and it should not be a ground
rod problem.


OP did mention some 220 volt loads which work fine,
which suggests it's a problem with the neutral.

What comes to mind, here, is for the OP to check
the neutral line, and look for open or corroded
connections. Figuring of course, that there "is"
a neutral. With his mention of three wire, might
be two hots and a ground.
