The
following signatures are for the
outguard HP-16 circuits.
The
signatures are taken with
the start/stop inputs of
the signature
analyzer connected to
A3TP4.

*To obtain this signature, a 10 K
resistor must be
connected
between the
S
voit TP and the probe tip of
the signature analyeer.
To
check for proper logic tracer
connections verify
signature of +S
V
test point Is
79FV.
