For cleaning things like this I cut bristles of an acid brush a bit shorter to stiffen it up a little and use some electronics contact cleaner spray or just 90% isopropyl and compressed air.

Excellent picture!! Thank You for finding it and posting. It adds some meaning to the schematic and illustrates the simplicity of a "sampling circuit".

Thanks for the clarification on the potting and the high voltages. I had/have not opened one up to check the actual construction, it was just a guess on my part, having seen other types having been potted. I edited my post to "possibly" potted but even that doesn't apply here.(y) One would...

This picture is a basic explanation This is what a "current transformer" looks like schematically. The windings through the hole in the current transformer would represent the "Primary" winding in the picture and the secondary windings would be the studs at each set of loops. The reason...

Bopping anything with a rubber mallet isn't going to resolve the problem. Lots of those connections on the terminal strips look dirty/somewhat corroded. I'd follow the schematic, verify the wire number on each winding of the current transformer and make sure they go to their appropriate...

Directly underneath that current transformer is a favorite place for mice to build a large nest. Along with that comes their urine and turds. When you pull off the cover, check the cleanliness and tightness of all the connections on the terminal strip below the current transformer.
