Just a thought that might not be relevent but on the build of my A10 the dynamo had not been used in God knows how many years and according to what I have been told the field coil core loses its residual magnetism over time. I replaced the bearings with sealed ones, fitted new old stock Lucas brushes, checked the resistance of the field coil and the armature after a light skim and undercut segments looked really good. On assembly used my variable speed drill with socket on the shaft nut and checked with an analogue multimeter........1.5~2.00 volts!!! "Flashed" the field coil with a lead from the battery plus a + lead from the battery to the case and then ran it again with the D and F terminals bridged together and got 25 volts on the meter!! Had a good nights sleep after that *lol* Gerry
