To improve the DU-5 fitted on my 1927 Henderson De-luxe I decided in rebuilding it with a modern style electronic regulator. This in addition to improving the charging make it a two brush generator where the field is controlled by the regulator.
Such a modern style regulator is availiable from; http://www.splitdorfreg.com/
Further knowledge on the Splitdorf generators and magnetos used on US made motorcycles; http://www.splitdorfreg.com/Blancard/index.htm

Generator all apart

New regualtor installed in Generator end cover

New magneto bearings from England. These bearings require the generetor or magneto endcover to be shimmed to get proper fit on bearings

Ready for installation after commutator is trued

Generator endcover with brusholders after mecanical cut out is removed

Using my thrusty ol Mayford to make replacement screws for all electrical connections


All done and ready for testing

Testing the charge current at approx 1400 Rpm

Really nice work mate... well done
