GMC Truck's 1991 Electrical Diagrams and Diagnosis manual (X-9140) for R/V and P models. An introduction explains how to use the book, electrical test equipment, wiring repair and connector service, special tools and the RPO and abbreviation lists. Three model sections follow, each with its own page numbers: Section A for R/V trucks, Section B for P commercial models and Section C for the P motorhome chassis. Every section opens with phantom views, a symptom index and power, fuse and ground distribution, then gives circuit operation, circuit diagrams and diagnosis charts system by system, and ends with component locator views and index. A general index closes the book.
