Just had a idea... but perhap i have had one too many to night...
Keith we could use a current coil though a anlogue multiplexer into a
analogue port on the pic. At each shutdown i could measure the
current in each channel at a low level and compair it, that way i
could detect a blown bulb even if there are others on the same
channel. Am i good or am i pissed.
