Powerlite's "Dynalite" range of alternators is made to look just like an original dynamo, err, generator. You get the best of both worlds: original appearance coupled with 80 percent more power, up to a 50 percent weight reduction and a unit that actually charges at all rev ranges! You must re-use your original pulley. Available in positive ground versions for otherwise original cars and negative ground for cars that have already been converted. The C42 generator this unit replaces was fitted to 3.8 E-Types from: RHD OTS 850092; LHD OTS 875386; RHD FHC 860005 and LHD FHC 885021. For E-Types, it will carry the Lucas number of 22902 on the generator body. It also replaces the Lucas 22902 generator fitted to later MK II and 3.8S sedans without power steering.
