My 86 GL Syncro (build date 11/85) suddenly lost its headlights,
although the high-beam lamp on the dash stays lit.  Some quality time
with the Bentley and a test light shows that the hi-low beam switch
seems to be the culprit - there's power at all terminals when the
headlight switch and ignition switch are on.  When the headlight switch
is off, though, 56a and 56b show power only when the lever is pulled.

There's power at the outlet of each fuse, heading towards the
headlights, but no discernable power at the lights themselves, although
I'm not sure the test light was getting a good ground.

If it is the hi-low switch is bad, how do I R&R?  Or am I barking up the
wrong tree?

Many thanks in advance -

PS - it's surely a result of the engine conversion :-0
