Upgrading Your Classic Car Dynamo to an Alternator

Dynamos offer a perfectly serviceable system for classic cars that are used infrequently, but if you use your classic car often – and especially if you drive at night, have added accessories or even use things like sat navs and mobile phone chargers – that system will start to struggle. An alternator is the modern answer to classic car electrical charging problems and can be fitted easily either with a proprietary kit or with a little fabrication. This Skill Shack video tutorial will show you how to upgrade from a dynamo to an alternator and will share hints and tips along the way from fitting brackets, wiring and other considerations like fan belt size and ignition coil positioning. We recommend for owners of older classic cars, that you first view our video on converting from positive to negative earth before undertaking this project.
