Let's say you don't know which color is which?

[chcjunior]

I just realized I don't know which color stands for what on my G&L hand wound Alnico buckers. I just left a voice mail looking for some assistance, but in the interim; Wire colors are red, white, black and blue. Initially I was assuming that blue replaced the Duncan green...but how can I verify this? I'm assuming a multimeter would come into play.

Well, finding the codes would obviously be the easiest solution. Aside from that, you can twist two of the wires together and measure the resistance between the other two. Try it with all combinations. The ones with the highest resistance will be your hot and ground. The ones with a lower resistance are the individual leads for each coil.

yeah, you can try that

you might also want to isolate which pairs of wires belong together

i am still not clear on how to go about figuring out start end / finish end without wiring it up and listening to how it sounds or if there is hum

according to the dealer: on the screw coil, black is start and red is finish. On the slug coil, blue is start and white is finish.

I'm not sure how this translates into tap, ground, and hot.....but now I know which color is the equivalent of Duncan buckers:

Duncan: Start Finish
screw: Green Red
slug: Black White

G&L: Start Finish
screw: Black Red
slug: Blue White

"Tap" would mean to split the bucker by wiring either the Red & Blue wires together & make a switch lead them to ground, or White and Black, depending on which coil you want to tap... of course you could also reverse the wires and.... ok

Btw Either I'm just confused or the Duncan data can't be correct, cause that doesn't seem to make sense to me because if you wire two things in series, you put them start1->end1->start2->end2 and not start1->end1->end2->start2.... this would cause phasing issues if I am thinking correct (Assuming that the two coils are already RW/RP to each other)
