I had a request to put these diagrams here on the 914club board. These are the 74 model diagrams and I have added annotations to them to make them easier to locate parts and understand the wiring. I've also added notes for things like replacing the dimmer relay. I did these about two years ago because I was going nuts trying to find things on the diagram all the time. I printed these with a good color laser and put them between sheet protectors. They sure come in handy. I have also stitched them together as a PDF file, but I find the individual pages are easier to read unless you have access to a big printer.

If there are any notes or changes you'd like to see then let me know. Hope these help with your frustrating electrical problems.
