<VV> Electrical gremlins with '63 vert

[John O'Harra]

I recently had some body work done (sandblasting floorboards) and when I 
got back home I noticed that neither the headlamps (hi and low) nor 
brake lights were working.  The running lights and reverse lights still 
work normally.

There don't appear to be any severed wires, and I replaced the bulbs and 
fuses, but still no joy.  What else should I look for?
