Vauxhall Velox and Cresta PA 1957-1960 Electrical Service Training Manual | PDF Download

This is the Electrical Equipment, Ignition and Instruments volume (TS.407) of Vauxhall’s five-part Service Training Manual for the Series PA, covering the Cresta (PAD) and the Velox (PAS).

It covers everything electrical, from the battery through to the dashboard. Each system is explained first, then taken through testing on the car, removal, stripping, inspection, reassembly and refitting. It also has a trouble diagnosis section at the front, so you can start with the symptom, such as a flat battery, a starter that won’t engage or a dead fuel gauge, and be pointed to the likely fault. The full wiring diagrams for both cars are at the back.
