    Slug coil on the humbucker is the problem. The neck Scrapyard Dog + neck reads: 1.3m ohms and up - it fluctuates.

    Screw Coil - 4.69k ohms
    Slug Coil - 0.9m ohms and up- it fluctuates.

    As a test i'm not making a schoolboy error the bridge pickup comes in a 12.7 kohms.

    Not sure why it is reading high in Mega ohms - does that indicate a ground fault?

    It indicates an open circuit - infinite impedance - with a tiny bit of spurious fluctuating reading caused by stray voltage being picked up in the coil.

    Get in touch with Ash, I'm sure he'll be able to sort it out.

    The good news is that the switch will be OK, it would be extremely unlikely for two faults to occur independently. Not sure why you originally got some buzz from the black wire when you touched it, just one of those oddities which confuse things...

    Pickup issue solved, @Elwood returned the pickup to me ... arrived at 9.00 this morning, traced the fault and returned it fixed by the 11.00 post Special Delivery ... under my 'lifetime guarantee'. :-)
    Sorry dude, sometimes these faults can appear ... even though we DCR test every pickup before packing.
