Thanks to everyone for the feedback. I've manually drawn in the diode symbols at the contactors/relays which I think prevents the previous shorts but still provides power to the coils when the switch(es) is (are) thrown. I also updated the electronic ignition wiring to comply with the instructions from Lightspeed and redrawn the regulator & low voltage part of the schematic and replaced it with B&C's LR-3C regulator+OV protection+UV warning. The new .pdf file is attached (still under 1MB). Any additional comments are most welcome.  Thanks again.

Lincoln,
The dynamo relay has a missing diode from the N.O. terminal to the coil. This diode allows the relay to be energized from the dynamo power even if the battery and main alternator are completely dead. If you do not want to use this diode, then the other diode that connects to the COM terminal is not needed either, although it does not hurt anything. Either both diodes should be used, or none at all. Using two diodes allows the dynamo relay to be powered by two separate sources without connecting those two sources together until the dynamo relay contacts are closed.
