You can use a cheap a$$ Harbor Freight meter to test what side does not conduct.

That's what I usually end up doing, but it adds another step to the process.

I like the idea of making a jig though. I like making jigs.

Use an Optivisor Luke.  :)  Those insulators can't be *THAT* invisible.

If you really like jigs, it would be easy to put a piece of sectional track on a table power one rail with track power running through a 12v light bulb, leave the other lead ending in bare conductor. Put a wheel set on rails, touch the axle with the bare lead, and you know which wheel is insulated.

If you really want to get fancy, power both rails through light bulbs with the same polarity/phase, and the axle lead with the other polarity/phase, and the side that lights is not insulated.  This does guard against the (remote) possibility that neither wheel has a good electrical connection to the axle.

A jig might be fastest if you need to do hundreds of wheels.

But, for simple, Pete is right - may the Optivisor be with you always.
