Have you made a visit to the site at that time? Is the wiring in conduit or
is it free run. Something is happening at that time to effect the system
and/or the resistance on the wire. Pumps turning on (surge), boiler pipes
heating up, generator tests, etc. Something may become very obvious to you
if you are there during these times. Set up a temporary wire to those
devices at lets say 11.30 at night so that it doesn't effect JQ public. Let
it go through those devices between the times you have narrowed it down to.
That way the exiting wire is eliminated from the system. It seems you have
eliminated the other obvious possibilities. Are there different makes and
models of equipment on the same zone? It seems that you are right on the
edge of the resistance tolerance and the slightest difference will put it
over the top.
