Note, I have redrawn the diagrams which were originally drawn by Robert Nuckolls of The AeroElectric Connection. These drawings reflect the Dual Battery Single Alternator system, and were done in Adobe Illustrator so you should be able to edit these drawings in either Illustrator or Corel Draw.

The drawing size is set for my printer which is Universal Size (13" x 18.5"). You should be able to resize the drawing to fit your printer.

If you have a problem I can be contacted at.
