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 C45 generator this unit replaces was fitted to all XK-120, XK-140, XK-150, MK VII, MK VIII, MK I, and early MK II with the Lucas 22496 generator and manual steering. It was also fitted to 3.8 E-Type up to: RHD OTS 850091; LHD OTS 875385; RHD FHC 860004 and LHD FHC 885020. For E-Types, it will carry the Lucas number of 22531 on the generator body.
