Hi all,
Odd problem with my blacktop stratocaster - initially the volume knob would turn the volume down but never all the way to zero. Now the volume knob does nothing at all. Wiring diagram is below.
With a complete circuit, I measure about 8kOhms between each of the three volume pot lugs, in any combination. If I lift the leftmost wire from the volume pot, the resistance goes back to normal (500K across the outer lugs, 0 ~ 500K ohms between centre and outer lugs depending on where the volume is turned to). If I measure that lifted leftmost wire to ground, I get that 8kOhm reading again, which doesn't really make any sense to me at all.
The problem happens regardless of where the pickup selector is, or where the tone pots are set to. Any idea what is wrong? I'm struggling to deduce where the problem could be if soldering that wire brings all the lugs down to 8K.
