vhII coil readings (didn't test which coil is which, so I'm calling them by the wire colour):
bridge "red" coil 4.2k
bridge "black" coil 4.84
neck "red" coil 3.68k
neck "black" coil 4.49k
To quote from the BKP FAQ:
"What is the Bare Knuckle Four conductor colour code?
Answer: Black =start of screw coil
White = finish of screw coil
Red = start of slug coil
Green = finish of slug coil"
Which means that in this model for both positions the screw coil is the hotter one, which I can imagine provides for a more balanced operation for the various coil splits.
