Ignition battery

[Andy]

IBBS powers several units in the G3X Touch system. These units are - GDU 465, GEA 24, and GSU 25. These 3 units each have 2 power input pins. One is conncted to IBBS and the other to MAIN bus. None of these connections plays any part in powering the electronic igintion system and the ignition wiring is not shown on the G3X schematic (some alerting/status signals are shown).

The ignition system wiring is shown in drawing set CC11-CCX MAIN SCHEMATIC on the page named -105 CC11-160 IGNITION SYSTEM. An insert on that page named -107 CC11-160 IGNITION SYSTEM BACKUP BATTERY shows the emergency ignition switch and the backup battery.

Let me know if you have questions after you have located and studied drawings -105 and -107. I have lots of comments on my copies of those schematics.
