The first thing I would advise you to do is unhook the connection to the fence. If the bargraph returns close to where it was when it new, there is a problem with the insulators or something making contact with the fence. It well could be a storage capacitor, but normally they do not sell parts for them. They often will have electronics that have no information on them to identify what their value is. Then it can become a guessing game to figure out what the part's value is. Many times they encase them in epoxy or like products to limit access to them. Needless to say they make their repair very challenging. Often the only way to fix them is trial and error. I can remember working one many years ago, that i had set so high, it would knock you down if you got closer than 6 inches away from it. It made a real pretty blue glow around the wire on humid nights. Check the charger while it is not connected to the fence. If it reads higher the charger is not the problem. If it still reads low, open it up, tell me what you see, and we will go from there.
Normally they produce 8KV plus or minus 2KV with no load.
