Ibanez 3 volt IBZ-LZ active pickups: white wire does what? Can they run at 9 volts?
I've got a pair of Ibanez "IBZ-LZ" active humbuckers that came stock on an Ibanez ART300 guitar and am trying to figure out if the wiring coming out of each pickup allows the two coils to be split or not, or coil tapped?
Based on my notes from how these pickups were originally wired up in the guitar they came out of, this is what i know about each wire:
GREEN - hot
BLACK - coils' ground
BARE - cover's ground
RED - battery power
WHITE - ????
in the OEM wiring scheme, the two White wires from each pickup were connected to each other and taped off. I have no idea why or what this means about the White wires' function. I don't know if it is related or not, but the only other time i have seen this configuration, is on a pair of *passive* Designed By EMG humbuckers that came stock on an Ibanez RGR320EX.
So, looking to know what the White wires do and if i can wire them for any options - like coil split/parallel/coil tap etc.?
Second question: does anyone know if these active pickups can be run at higher voltages, like a 9 volt battery instead of the stock 3 volt option? I searched around the net but found nothing that addressed these specific pickups. Apparently Ibanez has designed different pickups through the years but used "IBZ-LZ" in the name of these different pickups. Some were passive but there was an active EQ control/pot in the wiring scheme, some were a design that were made by Dimarzio for Ibanez... so that adds to the confusion. Again, the ones i am asking about are definitely active, run stock at 3 volts, and there is no active EQ or active control elsewhere in the circuit.
