Hi,

Yes move the capacitor over.
From the look of those brushes you got all of the life out of them as they were arcing for some time.
Having deep grooves in the slip rings of the rotor means the slip rings are done as well.
If you can draw your finger over the slip rings and can some feel sharp edges they are deep and near the end of life.
New brushes will have trouble get in there and seating properly.

It was a wise move to got to the Bosch rebuilt and steer clear of the other rebuilders.
I do my own rebuilding including the regulators brushes for less than $2.
The slip rings change out is a little more involved but doable with understanding and practice.
I believe Art has done one and he may have pictures on cleanflametrap.com.

You can check the capacitor with an ohmmeter by putting the leads on one way and then reversing them back the other way.
You see the numbers flash on a digital meter or will change rapidly.
The needle on an analog meter will deflect greatly on discharge and go to zero when current ceases to flow.
I think an analog meter is more meaningful in a sense it shows the charging changes more gradually or slowly.

The actual capacitance value is not so important but getting no readings means its completely open.
It’s purpose is to suppress the arcing and/or shunt any frequency from going out onto the B+ supply to the radio.
So maybe it’s done or was being overwhelmed.
Change it over to see or listen for it again. (:)

With new components it can go either way so the capacitor is not so much to worry about.
If you still get noise the capacitor can be substituted with one of most any size or value, that’s good.


Thanks for the update!
It will be appreciated by all.
