I have a cheapo multi-meter and I can't get it to read anything. I ordered a cheap $12 pickup online so if that fixes it I'll look into a good pickup. I still don't understand why it only hums in the full bridge position. One click up it should be using bridge and middle but the noise goes away. Maybe it pulls power from the bridge and quietens it down?

There is no "power" there, pickups are passive. When you can't get a reading, it's a rather sure sign of a short circuit in the coil. Best thing is to replace it, it's not an especially good pickup anyway.

I love new pickup day.
Not as much as I love New Guitar day, or New Amp day.
But, New pickup day is still a good day. My weakness is MJ made Seymour Duncans, LOL.

I had my old pickup out trying to get some kind of stable reading with the meter and happened to notice bare wires shining right where they come out of the pickup. I don't know how it happened but it's cut through the outer coating and into the wires about 1/8in. long. Oh well, I guess they were shorting against each other. One more thing to ask: I noticed my tone pots are marked D500K. I've never heard of a D letter pot just A and B. Also my tone knobs never seemed to change the sound at all. New pots are cheap and I'm already in there. Do I need to throw the D pots away and get new ones?

Are they both d pots or only 1 of them? If you have an a or b, you can use the d as volume and use the a or b as the tone. You are correct in that using the d pot for tone won’t really work to affect the tone.

I should note that a pots are usually used for tone, and the b for volume.

My volume pot was replaced a while back with a B500, I'm not sure what it was originally. Both my tone pots are D500K so I'll find some A pots for those. I'm also looking into replacing the 5-way with a 3-way switch. I hate the #2 and #4 selections anyway and never use them. I've had the guitar forever and it isn't worth much so I'll make it the way I want it. I know I'll have it forever. I can't get rid of something I've had for 20 years already. I'm sort of a hoarder that way.

Well I have it all back together now. I literally changed everything: Humbucker, all 3 pots, new jack, everything except the 5-way switch and it has the exact same hum.
SON OF A!!! I guess that will be the next step in diagnosis. It was quiet as a mouse until I put the strings back on. I did notice the middle single pickup does nothing. Even tapping it with a screwdriver it makes no sound. Maybe the switch on it too but it doesn't really seem to be magnetic anymore. On the plus side the tone knobs actually change the tone so that's something and the GM Hexbucker sounds incredible for $12. No comparison against the stocker. Definitely not a '50s sound but I got a Fender Starcaster for $40 that sort of has the right vibe. If the hum was due to interference or lack of shielding it would do it with all the pups correct?

Is there a ground wire on the spring claw?

Yeah, the main ground goes to the claw. It's just a small solid wire with no covering of any kind. All the grounds on the inside have a clothy covering. Is the claw and adjustment part or should it be tight? The two screws that run toward the neck side to hold it could be turned in another 1/4 inch. It's not gonna fall off but it's definitely not tight.
