Silent Circuit Wire Colors

[Steve Nukather]

Red goes to battery
Black is ground

So we're left with Yellow, Blue, and Violet. What is the function of each of these colors?

Yellow - switch terminal
Blue - Black wire of neck and bridge pickup
Violet - Black wire of middle pickup

 

[Steve Nukather]

So the Yellow wire's purpose is to switch the silent circuit on/off? For the Silent Circuit to operate, it appears the Yellow wire should not connect to anything.

The Blue and Violet wires seem to be the dummy coil outputs. Blue for regular polarity and Violet for reverse-wound-reverse-polarity?

All three pickups run through the silent circuit. Middle pickup is rwrp so it has a separate connection. The yellow is basically the black wire of the pickups.

I initially thought the same thing about the Yellow wire, but this schematic shows the Yellow connected to nothing.

When yellow is grounded the silent circuit is defeated. In teh above diagram it's conveniently connected to nothing (rather than flap around). It is active in all positions, except that in positions 2 and 4 which are naturally hum-cancelling also it cancels itself out too! Smart! In more complex wirings, a one pole of a superswitch can be used to turn the silent circuit off when needed (i.e. when using non-humbucking pickup selections). See post #7 here....

The pickups and silent circuit are grounded through the black wire, and yes, blue connects to the ground wire of standard polarity pickups, violet to RWRP.
