Chasing a p/u selector switch short on a modded JTV-69

Recommended Posts

Hey all - 

 

Does a magnetic pickup setting short that doesn't appear to exist in the same position using Variax (instead of magnetics) generally mean there's a wiring problem on the magnetic side? 
Or does that generally mean the 5 way switch is faulty? Not seeking a concrete answer - more like a "What are the chances of A versus B?"

Background

I have a JTV-69 with JBE pickups in it, and at a gig last weekend the middle pickup (when playing magnetics) crapped out.
Was able to get sound via the piezo/Variax with the switch in the 2, 3 and 4 spots, but I know the switch doesn't behave like a normal 5 way so I don't know what, if anything, that means.

 

Before I go through the production of taking everything apart, would like to know the odds that it's a wiring problem versus a switch problem - reason being the PCB replacement parts are on back order at Full Compass. If it's likely to be wiring, I'll just try to chase the short with my multimeter, but if it's likely to be a switch issue, then I'll wait until I get the replacement parts from Full Compass.

The pickups were fine for years; the only thing I can think of is that the gig I played at was outdoors and it was a chilly (40-50 F) day, so maybe the failure was weather-related.

Something intermittent in the 5-Way switch. Contact cleaner won't fix it.

Will need a service center trip.
