ELECTRICAL GREMLINS [OVERCHARGING 440-3]

I appreciate you greatly for your kindness and patience. I tried my best to make it easy to diagnose!

I do have one more question however, I was looking into replacements and saw these... how do you feel about these? I'd like to be able to tell if they're grounded or not and was hoping you could help!

I BELIEVE these are all similar, but I know you all could help me figure that out! I know NAPA may not be the most Ideal brand but it's in stock near me, and I'd love to see if it fixes all of my issues!
Why can't you fix what you have now? Maybe a better question is, can you post a clear close up of your brush holders, maybe we can see what it/ they need
