R 50 S Charging issues
Posted: Tue Nov 09, 2021 12:51 pm
I have a R 50 S fresh restoration and when I slightly rev the throttle the charging light goes out. When I rev it higher the charging light flickers. I put both an analog and digital voltage meter on the battery and it registers 6.4 volts DC before I start the motorcycle, 6.5 at idle and 6.7 at higher revs when the light is flickering. This is not close to the 7.2 that is expected.
The components installed are as follows:
1) A new solid state voltage regulator.
2) New brushes.
3) A cleaned up armature of unknown origin as it was removed from the motor and in a box, but I believe it is for this particular motorcycle. I tested the armature and it tested fine. I cleaned the armature segments before installation.
4) A cleaned generator of unknown origin as above and I am not sure if it is for this particular motorcycle. I tested the coils and the resistance tested good.
The generator shows the part number: IJ/CGE 60/6/1700R5 on the case and I see no "Bosch" name on the generator at all.
I am thinking I have a mismatched armature and generator, but I am not sure if that would cause this issue.
From the part number above, it looks like 60/6 would be 60 amps at 6 volts, but that may just be wishful thinking.
It could be a bad voltage regulator, but it is brand new and I would think it would be reliable (hopefully).
Any thoughts are welcome!
