1990 Chevrolet R/V and P Truck Electrical Diagrams and Diagnosis

Chevrolet's 1990 Electrical Diagrams and Diagnosis manual for R/V and P truck models. A short introduction covers how to use the manual, basic electricity, test equipment, wiring repair, Weather-Pack and Metri-Pack connectors, special tools and the RPO and abbreviation lists. The book then splits into three sections with their own page numbers: Section A for R/V trucks, Section B for P trucks and Section C for the P chassis. Each opens with a phantom view, symptoms index, fuse block and power distribution, gives circuit operation, diagrams and diagnosis charts system by system, and closes with component locator views, bulb data and a component locator index. A general index ends the book.
