Lister Based Generators / Engine/Generator for Sale
« on: May 08, 2023, 01:06:52 PM »
I am selling my generator/engine. it has been in the same shed since it was installed, new, in the 70s. I have the original handbooks for the generator and the engine as well as a separate instruction book and parts list. it starts easily using a battery or crank. it has been well serviced and used very lightly. Run monthly for 30 mins or so and that is it so very low hours. i attach some photographs but feel free to ask away if you are interested in buying it. i thought i would advertise here before going to somewhere like eBay. buyer dismantles/collects for Berkshire, UK. Not sure what I want for it yet as i simply don't know what it is worth!

Well thanks for that....if only we had something like this in England....perhaps we do and, if so, I hope someone can tell me where they are!!

Thanks for the advice....I am looking for a company in the UK that can take it in and recondition/mend the thing for me as I am sure the whole unit need skewering etc!

Thanks for this.....Meccalte weren't offering to rebuild it but they said they couldn't replace it either. Happy to get it rebuilt but I need someone to do that as it is way beyond my capabilities so again, any pointers as to who might do that would be appreciated.
thanks

Lister Based Generators / Replacing Generator
« on: June 02, 2020, 11:14:26 AM »
I have decided to replace the Brush Generator(alternator?) attached to my lister engine with a new one. Can anyone tell me who, in the UK, i can contact to source an equivalent? I have been in touch with Meccalte and they say they cannot help. I attach a couple of photos. Any help/advice would be grateful received! many thanks. Alex

Hi there...apologies for the slow reply. I have just sent the scans to you in 2 x emails! regards, Alex

Thanks Bob. One question, is there an easy way to dismantle it? I can’t see an obvious way of gaining access to the internals!

Hi Bob

great news....it's working. I attached a lamp to the red/black outputs in the top box and the bulb is burning brightly! Thank you for all the help with this, I really do appreciate it. OK, my next project is to strip it down and rewire everything....it is filthy and some of the wires have been nibbled by mice so it is long overdue. What do you think? I can't see how to open it up for a start and, secondly, don't know which wire is should be looking to buy....
thanks
Alex

Hi Bob
no continuity between 13 and 19 (the battery negative input)
no continuity between 22 and 16 / 17
The engine turns over ok with the starter pressed down.
when the problem started originally it was generating fine but i let it shut down whilst still connected to the house so i feel everything is ok albeit a little antiquated? what do you think'?
thanks
alex

ok i have continuity between 13 + 14 but it is up at 112 ohms! 13 + 15jumps up to between 40 - 120 ohms then back down to 1 straight away. i can't get continuity between 13 + 16 and between 13 + 17....... I am beginning to wonder id i should strip it down and rewire it?! thanks. alex

Hi Bob and apologies for the delay in replying.
Ok, I have done everything you asked and the readings were slightly higher than yours. However, on the final task (measuring between 1 to 13) things go wrong. the meter jumps to about 26 ohms instantaneously and then drops back to 1 .....i feel the whole generator probably needs rewiring!?
thanks

Hi Mike, if I ever get the time it might be worth doing a complete strip down and rebuild of my Brush generator head. I could then post photos, wiring diagrams and resistance figures. There seam to be quite a lot of these generators still in out there.

Hi Alex, I was a little baffled by some of the readings you sent me. Having studied the wiring in your top box, the neutral and positive AC outputs on yours are different to mine, reversed. Thus 1 and 13 are reversed on your model. Please check the resistance between 13 and 2, also the resistance between 1 and 12 and get back to me.

The other thing that concerns me is that you do not have continuity between the slip ring (11) and the brush holder (12), could you please check the condition of the brushes, holders and wiring connections then check the resistance again.

Bob

Bob

 I have the readings.....between 13 and 2 is 1.9 ohms and between 1 and 12 is 0.5 ohms......
As the neutral and positive AC outputs are opposite to yours, could i have put everything back together back to front when i replaced the bridge rectifier etc?
I have checked between 11and 12 again...it shoots up to a reading between 107 and 170 ohms and then drop back to 1 ....
i am confused!

Bob

Please do not feel that you have let me down.....quite the opposite!
I will get back ASAP with the resistance readings and we can take it from there.
thanks again
Alex

I look forward to this....I feel it wouold be best to strrip mine down as there is so much cr#p in it (dust etc) and some of the wires have been chewed. Perhaps I should do this anyway so we can get some decent resistance readings using the new wires, screws etc?! I might as well paint it at the same time! Mechanically it is fine and was generating electricity perfectly until i let it run down with the load still attached. I am not worried about powercuts so don't have to wait to do the job (and its not generating anyway as you know!)
