As noted, never had one w/ the light interlock to have had the
opportunity to fiddle w/ it, but would seem that would be wrong set of
leads to short -- I'd think there would be a completed circuit via the
emitter/sender unit from one to the other. The inputs at the unit
from the interlock would be where I'd do my jumpering...again, this is
surmising w/o direct experience.

Did you try the lens-cleaning and the direct-coupling alignment/
sensitivity experiment(s) suggested?
