The back plate on my Series bass seems to be shorting out the bridge pickup, it makes a crackling sound when I move the plate round when trying to screw it down. It does not happen on the neck pickup. I moved the bridge pickup wire on the board a bit to see if that was the cause, but that did not produce the crackling sound.
I can't see what components might be touching. Any thoughts on how to resolve this? Is there anything I can place between the back plate and internal components to insulate and prevent touching?
Thanks.
Look closely at where the backplate mounting screws pass through into the cavity, particularly near the 1/4" jack. Not much clearance there. Just an idea.

Thanks for the suggestion, Jimmy.
It happens with and without the screws inserted. I want to try placing some insulating material between the cover and inside components, if it continues then I can rule out the plate and PF6 card components touching something inside.

I put a thin piece of plastic sheet between the PF6 board and inside components, seems to have solved the issue. If the crackling occurs again, then the cause is something else. I hope this has solved the issue.
Just a thought; is the preamp board secured snug to the backplate? If it's got a bit of wiggle room, might be just enough to touch something.
Or wiggle that ribbon connector to test... I only ever un-did mine once. Kind of a trick getting it back.
Thanks, Greg, I tried all that. Putting the plastic Teflon sheet in between seemed to help. Fingers crossed crossed :)
Interesting. I just wonder what could've changed the tolerances? [shrug] At least you found a simple workaround.
