The other symptom many of us see is the airbag
light that takes up to a minute to go off. This is mainly
due to the deterioration of the ni-cad battery pack
that provides temporary power to the ignition
circuit in the event the main battery power is
lost just prior to the crash.
I have often thought of hand building up such a module, but
never "gotten around to it" given the continuous stream
of higher priority projects available.
