Thanks for the response.
The problem diesn't result in a 'dead cut' when selecting the rogue
unit - just a drop of about 200 RPM (as opposed to about 75 on the good
unit). The fault also only seems to happen when the engine is up to
temperature (which makes ground testing significantly more difficult).
Both of these lead me to believe that the problem is inside the box
(though I suppose that it is possible that as the engine comes up to
temperature, the insulation on the wires softens and the resulting
increaded allows a damaged wire to move more than when cold).

Peter,
This is a well known problem with the older 4 way plug versions.
Before
you shell out for a new ignition unit, take a good look at the flying
leads from the "black box" to the connector.
The prolonged vibration tends to work harden the copper leads and
they
eventually fracture within their plastic sheathing (hidden from
view),
making intermittent contact.
I won't pretend that its easy to spot, but it's a lot cheaper than a
new
unit!
