Yes. This system has been in place since 2002. All of a sudden parking lot lights do not go on. I checked bond in xfmr, and also followed electrode back to main. First thing I checked after reading screwy voltages.
I believe it is in the xfmr coils themselves. I removed HV wires off xfmr lugs for giggles to see if voltage would change with nothing connected on that side. Voltages were the same.
