I am starting to explore the electrical system more and I need to see if someone might have a primer/reference source for our wiring diagrams. Our diagrams are nowhere near like the usual SAE wiring diagrams we routinely see. I took a copy a diagram to our chief avionics electrical engineer and he couldn't make heads or tails out of it. They have all kinds of crazy symbols and nomenclatures I've never seen before. Any help or leads would be greatly appreciated.
