Cort G250 Wiring Diagram

Seen below are the factory issued pickups and electronics of the Cort G250 HSS as received. I have also included a wiring diagram for your reference. Please take note that this diagram is an adaptation of "Wiring for Electric Guitar Cort G250DX" by Muhammad Irvan Fardani.

Shielding

The control cavity is shielded with conductive paint, and the back of the pickguard with aluminum foil. Control cavity shielding is grounded via a metal tab. It's all well and good, except for the fact that the conductive paint job is patchy with numerous bare spots; and the pickguard shielding only covers the pickup selector switch and controls. This being the case, we'll be redoing the conductive paint shielding, and applying full copper foil shielding to the back of the pickguard.

Pickups

Cort refers to these pickups as a "Cort® Alnico V H-S-S Set," comprising neck and middle single-coils; and a bridge humbucker. It's wonderful that Cort has put in Alnico Vs, considering the price point of this instrument. The neck and middle pickups feature white plastic covers and staggered pole pieces, while the bridge humbucker sports two uncovered slug coils; also in white. The height of all three pickups may be adjusted via spring-loaded height adjustment screws.

The neck single-coil has yellow and black leads, and is labeled "PTP1012-EG5-WHT-M." The yellow lead is hot/positive, while the black lead is negative/ground. DCR as measured is 7.03K. About the label, I'm guessing that "WHT" refers to the white cover, and that "M" means "Middle." 

Neck Single-Coil Pickup

Neck Pickup DCR is 7.03K

Next, the middle single-coil has white and black leads, and is labeled "PTP1009-EG5-WHT-F/R." The white lead is hot/positive, while the black lead is negative/ground. Once again, one may assume that "WHT" refers to the color of the cover, but what about "F/R"? Could it mean "Front/Rear"? Fueling my doubts is the DCR reading of 5.20K, which is way less than that of its neck counterpart.

Middle Single-Coil Pickup

Middle Pickup DCR is 5.20K

 

Moving on, we have a bridge humbucker labeled "PTP2037 EG4-WHT-R-2P" with a DCR of 17.22K. This humbucker features a cable with two core leads [white and red], and a stranded shield [negative/ground]. The red lead links the two humbucker coils. This lead goes to the sixth lug of the selector switch, and on to the coil-split switch. Meanwhile, the white lead carries the full [combined] output of the humbucker; and is wired to first lug of the selector switch. Please refer to the "G250 Wiring Diagram" for details.

Electronics

The stock electronics on this G250 include an Alpha B500K mini volume pot, Alpha 5P PCB pickup selector switch, push-pull tone pot with an integrated coil-split switch; and generic mono output jack. There is evidence of a botched soldering job with regard to the push-pull tone pot, such as burnt and/or melted insulation and messy solder blobs. In any case, only the tone pot is functioning, and nothing happens when the knob is pulled up. The owner says that he's never really used the coil-splitting function anyway, and now wants the electronics simplified and upgraded. Rest assured, he'll be getting what he's asked for.
