Hi Bob

Here is the link to the manual.

https://drive.google.com/file/d/1BBu5Z5CbzI7XI0-5yLBqb94Zl7q1BJqm/view?usp=sharing

its a good manual and has answered a few of my questions.
my wiring is exactly the same as page 4.
Regards
Al

Thanks Oldgoat.
You have confused me a little there.
You’ve listed 2 different items. Do I need both?
Could you explain a little further?
Thanks
Al

Many thanks Bob.
Good news I have found the manual for it online at “internal fire”
My wiring is exactly as page 4.
I note that you can fine tune the output by choosing different tappings from the transformers.
So my first task is to choose a solid state rectifier and wire that in. I need a bit of help here choosing the right one and working out which connections to use?
I also need to replace the suppression capacitors that run off the slip rings.
You mention that the enamel is not great, what exactly do you mean, what are the consequences?
I’m enjoying the learning curve on this project!
Regards
Alan

Hi All,

I have researched fitting a solid state rectifier and looks very possible. Unfortunately I dont have a manual , the only info i have is what is on the plates.

Can I fit an AVR? if so does this do away we the need for the rectifier?

Thanks

Hi
I have just acquired a Lister HA 2 cylinder with a Brush RS1B alternator generator.
(3 phase 15 Kva)  it hasn’t run for 10 years.
The engine started on the button.
At this stage I didn’t know wether it was capable of generating any electricity.
I fired it up and all went well, until after about 90 seconds I could smell that familiar smell of burning electrics so I shut her down.

It appears that the fins have over heated and taken out a cable and melted the connected block. See photos.
Only the 2 right hand front fin sets have over heated.

Some questions:

What are the fins for? Is it the rectifier/ voltage regulator?
Why might they have over heated, a short some where?
I guess it is not worth repairing.

Can I fit a  modern voltage regulator?
Should I consider replacing the whole alternator?
The lister engine runs well, no oil leaks and in great condition, spins a 1500 rpm.

Is this suitable?

I appreciate that there is some engineering required to mount it!

Any thoughts on this would be appreciated.
Thanks
