So this has happened to me a couple of times, and I have just done a jury rig to get me through, but I thought I'd start a discussion here.
I went ahead and used the Stew Mac grounding paint on the inside of my control cavity (and this has happened to me with copper tape as well).
Today, I was wiring up my jack, and it kept shorting out when I would insert it in its' hole in the body. I finally discovered that when the tab from the TIP would touch the inside of my control cavity, it would ground out. I taped the tab up and was able to insert it with no problems. To fix it, I went ahead and got some paint and painted the inside of the control cavity around where the jack goes in, and the problem is solved.
Has anyone experienced this, and if so, what did you do about it. Is there some sort of wiring configuration that causes this somehow? I haven't done anything out of the ordinary ground wire-wise with this bid to my knowledge.
Thanks!
