I have been developing a growing library of airhead electrical system documents. So far I’ve written documents that cover the /5 and /6 1975-76 electrical systems.
For each, I document the wiring system, circuit by circuit, with explanations of what goes where and with notes about well know problems. Another document describes how the electrical components work. I also wrote an Electrical System Basics document to help those who, like I was, are mystified about electricity and how it is applied to our airhead motorcycles.
I’ve been working on these documents off and on for the past two years and figured they might be helpful. You can find them using this link and they are listed on the right hand set of links on most pages.
I hope to add additional documents covering the 1977 RS and possibly the 1983 RS as I have both of those, have completely rebuilt the ’77RS and plan to do the same for ’83 RS soon.
I see more and more questions about electrical system problems, and I expect this to increase as these bikes get older. Many folks struggle with electrical wiring diagrams and don’t have a good understanding of how the electrical components work. So they are at a loss about how to proceed with fault isolation and problem solving. I found that writing this material helped me learn much more about the electrical system and improved by diagnostic capabilities. That’s one reason I wrote these documents; writing things down really helps me learn.
I’ve digested a lot of material others published, among them are Bob Fleischer, Duane Auscherman, Anton Largiader, Tom Cutter and many of the questions and answers that have appeared in the various airhead forums including the micapeak airhead news group and the BMW MOA airhead forum. To all of you, thanks for sharing your knowledge.
I hope this material is helpful. Have a great New Year.
