I bought an old cabin with a relatively new mast and meter base. Recently, Our lights wouldn't come on or were dim. I checked the voltage from the meter base where it connects to the buss bars. I have 213 volts on one and 27 volts on the other. Had no problems whatsoever last time we were there and then the next visit this situation. Any thoughts? It's a remote location and it's winter, so before I call the power company I want to be sure that I have covered all my own bases first. Thank you!
