There are a lot of good resources for Electrical and Vacuum circuit information. Much has been produced by Ford Motor Company over the years and yet it seems like this is one area most people have trouble locating the technical help they need.
I have searched for years to find the most and the best information possible to create a technical resource library for myself and in the process have come upon some excellent sources for this information. Some of this has been reproduced by various companies. Some of it is buried in a few pages of a big thick manal that was only available to the dealers. (These, by the way, usually got trashed when they became outdated).
The stuff that is reproduced I have available for sale and is listed on my Manuals and Literature page.
I also have copies of many of the large manuals that the dealers had. For the later years (70's and 80's) they had what were called "Electrical and Vacuum Troubleshooting Guides". These showed diagrams of the individual circuits in great detail and gave a good description of the steps to take to diagnose and repair the trouble with these circuits. For vacuum related troubles these books offer the only source of this type of information.
Free Technical Hotline
If you are having trouble with some of this on your car I will try to help you as much as possible by email or by phone but if you do not have any type of diagram or picture to follow you probably will not know what I am talking about. So to help us both I offer to make copies of the appropriate pages and send them to you. I am charging $1.00 per page to cover my costs and a bit for my time so I can continue to offer free technical help over the phone and by email. I can also fax these copies if you have that capability. I will trust that you will send a few bucks to cover my costs if I do this.
The phone number for help is: 715-884-6546
