Testing procedures for automotive AC and DC charging systems

Haven't seen this book since I worked for the author in 1976. It is a hardcover that covers theory beyond the needs of a repair technician. DC generator and alternator systems are covered. For me the best portion covered how electromagnetic regulators functioned and could be unsealed, cleaned and adjusted to operate to OEM specs. This is valuable information for the restorationist that wants to keep the vehicle "original".
