Ignition Sense (All Applications)
The radio, as shipped from the factory, has the "ignition
sense" feature disabled. As such, the radio will be
powered ON or OFF as determined by the front panel
ON/OFF/VOLUME control only (assuming A+ and A- are
connected). If it is desired to enable the "ignition sense"
feature, open the top cover of the radio and remove the
shield from logic PWB. Slide switch S951 from position
3-2 to 1-2. Replace shield and top cover. Be sure to apply
correct torque to screws holding top cover in place (refer
to the appropriate Maintenance Manual).
The "Accessory" point should drop to ZERO volts when
cranking the engine and return to +12 volts after the
engine is started. If a point is chosen that drops to a
voltage between zero and +12 volts, the radio might
execute a power-up cycle several times during start up. It
is recommended that the terminal be measured with a
voltmeter to be sure it shuts off (goes to zero volts) during
the cranking of the engine.
The fuse holder must be attached to the yellow sense lead along with the ring
terminal as follows:
1. Cut the yellow sense lead approximately 6-12" from the end that will be
connected to the ignition sense point.
2. Strip the insulation from each end of the short lead and from the end of
the long lead at least 3/8".
3. Insert the stripped end of the long lead and one end of the short lead into
the narrow end of each fuse holder half.
4. Crimp the leads in the fuse holder halves with a crimping tool.
5. Insert the 3-amp fuse into one end of the fuse holder and join the two fuse
holder halves firmly together.
6. Attach the ring terminal to the end of the short lead and connect this lead
to the ignition "ON" sense point [preferably an "Accessory" point (in the
vehicle fuse panel) that is switched on when the vehicle ignition switch is
in the ACCESSORY and RUN positions].
