Hoffberg 10kW and 3phase wiring diagram
« on: November 30, 2025, 05:55:10 AM »
Need help please. I just started to rebuild a VERY nice Lister ST3 with direct-coupled Hoffberg generator alternator.
The PO had disconnected the wires coming from the windings and brushes from the connector box on-top of the Hoffberg, and removed the box.
All the diagrams that I found on the forum are for generators up to 5kW but nothing for a 10kW Hoffberg.
Can someone please help and possible give me some guidelines for fitting a AVR?

Hi Ivan, I don't think you are going to get much info on Hoffberg from the forum.  Most of the members are in Europe or the States, and that alternator is a SA'n build.  I have a 4kw version on my SR2

Thank you very much - good advice. I'll try to find a local electrician to do the wiring.

Where are you?  I'm in Knysna.  There used to be a boffin on this forum from East London, name of Ed, but he hasn't been around for a long time.  Not many SA'ns here, a few have come and gone.

Good Morning. I'm based in Pretoria and have some help from VoltAmpere, but so far, nothing yet on the 3phase 10kva Hoffberg.

Hi Ivan, when you find anything on these alternators please share.  I too would like to spruce mine up
