Hi Bolens, you really need to give to give some of the clever dudes here a little more information. I am guessing that you have an alternator/generator built by Brush. These are interesting in that they built a generator, a dynamo and a starter motor all into the same unit.

My initial thought is that if it is only pumping out 12 volts, when it should be doing 110/240 volts, you have a wiring problem or are measuring the output from the battery charging circuit.

There are a great many possible issues please provide more information.

Bob

Hi Bolens

Put pics in "atachments", under 1MB, ~920kb (shrink with MSOffice pic manager - or other - resize and crop)

Hi Bolens

I'm sorry what I wanted to say was ~ 920 pixels wide.

I think the rear plate with all the brushgear can be rotated on that model You could try moving it a few degrees and see if there are any changes to output.

If you can find a schematic for that head I might be able to suggest troubleshooting via volt-ohm meter.  Checking continuity of output windings and field coil are one place to start.  Flashing (applying 12V) to the field coil on a long out of service unit is often required.  The regulation circuitry may have some failed components too, but I have no experience with this one.  Worth a trip to your local generator repair shop if you lack the skills, but finding the schematic may be essential for them as well.

Ajaffa put up a circuit which I think applies to your generator in a post started by Onzlow on Nov 21-2018.
