Bisonic grounding wire to metal mounting frame question

[lungimsam]

1. Why is that grounding wire from pup to metal mounting frame wire there if the pup has a ground wire to the harness anyway?
2. If my pole pieces are showing connectivity with the output jack, but the metal mounting frame is not, does that matter?

KEEP in mind the neck pup is RWRP.

Back strory:
I just noticed when I touched the bridge pup metal frame with my hand it grounds to me, but when I touch the metal mounting frame on the neck pup it does not.
There is connectivity from the bridge mounting frame to output jack, but not from the neck pup frame.
The neck pickup seems to sound the same as always.
Is it worth removing strings and going in there to investigate, or is that how it is supposed to be.

The metal pickup ring is grounded to act as a shield for stray interference from lights, dimmers, that sort of stuff. It doesn't sound like the pickup ring is connected to ground on the neck pickup.

Cool! I knew you would answer!

OK. So I will go in there and see if it came off, and also shield tape the pup like you did to my bridge pup while I am at it!
Just have to review the emails about where to put the tape.

Temporary fix til I can get in there after playing at church this weekend. I don’t wanna go in there and break something else before playing tomorrow and Sunday. Works good!

Pardon me for laughing but that wouldn't last more than five minutes with me playing. I use the bass side/bridge side corner of the PU as a thumb rest and sometimes move towards the bridge and the copper strip sure looks like something I would hit, eventually.

To veer, what was the screw hole in the vicinity of that corner for?

Haha! I play with a pick near the end of the neck and my right hand only touches the strings when I play. So that tape is well away from where my hand always is. Works for my style playing. practiced today with no issues. Good for now til I can get the pickup done up after the services this weekend.
For your personal use, you could just run the tape under the g string side of the pups, letting it adhere to the body the whole length. Then you would not snag it while playing.

Veer answer: That hole was a mounting hole for the old thumb rest as this was originally a Starfire I. I routed and put in that neck pup. You can see the other thumb rest hole on the other side, too.

Thanks . I figured non-fretting hand techniques were different. I wondered about a thumb rest but had forgotten you had done a I to II conversion which is obvious from the more complete pictures

I'm glad that works for you, but I need to come up with a more elegant solution than copper taping the underside of the pickup. One more year, and I get my freedom back...

Well, it’s inside the bass so no one can see it. I think the copper taping the back of the pup would be the most economical and least labor intensive solution for pickup production.
I forget what guitar it was, but there used to be an old (Gibson?) hollow body guitar that had a copper box that housed the electronics. Now that’s an expensive way to shield a guitar.
