Charging systems are always a challenge on old cars. Regardless of your plans to restore it or make it a hot rod, you’ll likely want to get rid of the old six-volt charging system. Stepping up to a 12-volt system is quite simple these days, and you can even keep the same old school looks of a generator with Powermaster’s Powergen unit for Ford Flathead engines. These units are designed to have the old school looks, but offer a one-wire connection and 75-amp max output! They are the perfect addition to a traditional-styled Flathead that will see some action on the highway!
