Circuit Operation
Battery voltage is supplied through the AUDIO MIR-
ROR fuse C–2, voltage is applied with the starter switch
in ON through the ELEC. IG. fuse C–15 and voltage is
applied with the starter switch in ON or START, through
the AUDIO fuse C–18. Battery voltage is applied to re-
tain the system memory and to power the clock.
Refer to Section 1A and Section 8C of the Workshop
