Title: Lister sr1 Genny
Post by: Bolens on April 24, 2019, 11:50:25 AM

Hi
Got one with a 220/110 output but only getting 12 v ?
Any ideas please
Thanks

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.

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.

Hi,yep reckon a flash is where it is at but first will try to locate genny specs .Got a plate on I am sure but will look when it is light.Is there a library on here of gen specs ?
Cheers

Thanks oldgoat .What model is it if you know ?
Just trying to nail down circuit diagram as don't want to fry if I flash .Pretty good nick the actual wiring in there and brushes look  ok

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

Thanks
Mine is not a start o matic
Handle start with de compressor
That is useful thou and many thanks for advice

Hi
Thought I had replied
Mine is a handle start so still unclear on diagrams?
Any help much appreciated
I can flash field but need to ID field wires for certain

Hi
Mine is manual start
Handle ?
Still unsure so any help much appreciated
Thanks

Hi Bolens, there are two basic types of generator, they both involve spinning a copper winding inside of another set of windings. In one type, the electricity generated is taken from the rotating windings, in the other type the electricity is taken from the stationary windings. Without a lot more information and photographs it is very difficult to determine which type you have and to offer any advice as to how to to flash the generator. Could you also please provide some information on how the voltage is regulated, I would expect that it probably has an old selenium rectifier and wire wound rheostats.

More info please.

Bob

Bolens

Is there a top box on this generator?  If so please take a picture of the top box internals.  In your first picture I can just make out a commutator that will be the DC power to the field windings.  If you are lucky it might even be a set of starter windings.  We need more clearer pictures to be able to decipher what you got.
