Amongst the new material given in the new Chapter the following may here be mentioned: printed and miniaturized circuits; modern alternator design and performance; improved conventional and transistorized ignition systems; new sparking plugs and batteries; quartz iodine head, spot and fog lamps; improved flashing indicator systems; multi-speed windscreen wipers; magnetic-pulse type speedometers and tachometers.
