Generator Restoration

The process start with completely disassembling the generator and then some preliminary test. I test the armature for shorts & opens and the field coils for electrical integrity. Once it is determined that the core is in a condition to be restores, all part are chemically and/or mechanically cleaned.

                  

On the left, the armature is electrically tested on the "growler" and on the right the field coil is tested with a precision ohm meter. Once these initial test are complete, the commutator is turned on a lathe and the wiring recoated with an insulating paint. The field coils are re-wrapped  if necessary and coated with an insulating paint.

Here are all the parts that go in the generator after the initial testing, cleaning and painting. New bearings and brushes are included.

The completed generator with end housing painted black and the generator housing painted with a clear coat for longer lasting appearance.

 

 

 

This is the final test area. The generator is clamped in the tester and driven by an electric motor. Voltage and current output of the generator are measure to assure that the generator performs to the factory specifications.
