Well I've been learning the hard way. I think it was having to understand my '84 SJ's wiring that forced me to think about what I was redrawing. I know at least few of you can kick my butt when it comes to electronics, especially the hands on stuff. I have yet to solder diodes into my alternators. That's on my to do list. (yea I know, its kindof silly, the square backs are better. I just would like to have them as ready to go spares and learn to do the work in process.)
