Generators / Lister LD18 SOM Wiring problem
« on: June 07, 2008, 09:54:26 PM »
Hi,
I have just bought a Lister LD18 and have found one brown wire hanging off inside the control box.  I cant seem to trace it with the wiring diagram.  Does anyone know where it needs to be connected.
Its in the set of 3 wires from th solonoid control on the engine to the wiring in the box.

Here is a photo of the machine. I will try to photo the offending wire tomorrow.


Please help

Hi Matt,
Thanks for the post.  You are right I have had a good look at the wiring diagrame and it does show power on the alternator. I also had it confirmed by Ken Boak.  He also tells me its 24V starting so it looks like I will need another battery.  I may even treat it to a new 24V one.  I think it deserves it after all these years.

If anyone knows anything about them please let me know.  Again Ken has kindly sent me loads of info of how they work.

Kind Regards

Stephen

Hi All
I have just bought a Lister LD 18 3hp Startomatic.
It looks complete apart from I cannot find a starter motor?? Any Ideas.

Does anyone have any documents or know of any postings regarding my new friend.

Kind Regards

Waste Vegetable Oil / Re: My New WVO Processor
« on: May 29, 2008, 07:42:47 AM »
Veggie, List,
I run 30-40% WVO to 60-70% diesel.  It mixes well. I even add the WVO after the Diesel and let driving around mix it.
The common rail Land Rover engine is a direct injection.  very high pressures involved.


This is a little experiment I did a few weeks back on WVO viscosity.  It was prompted by reading about adding acetone, but I now suspect that it just helps clean the injectors a little (my guess only)
Its a very simple drip test and WVO may act different under pressure but its the best I could do.

Apparatus:
1  x washing up bottle with the bottom chopped off, then invert so the little hole is at the bottom.
1 x measuring cylinder
1 x Thermometer
1 x Accurate weighing scales to help check repeatability of liquid measurement.
1 x Kitchen with wife absent at time of experiment (although she said it would have been nice to have helped)


OK I added 250ml of diesel to the washing up bottle and allowed it to drizzle out and timed how long the bottle took to empty.
I then repeated it with all of the below items. The experiment was repeated 3 times each and averaged the results.

Diesel @ 15c   30.63sec
vegoil @ 14.5c   1.05
veg oil @ 20c   49
veg oil @ 70c   33.45
new corn oil   51.31
   
veg oil 20% pet + 0.2 acetone   51.75
veg oil with 20%petrol   51.75
veg oil with 0.2% acetone   59.35
60% derv 40% veg    34.4  (similar time to veg at 70C)
   
   
veg oil with 20%petrol @ 70c   34.81
   

As you can see veg with acetone does not make much difference under normal conditions, it may have an effect under pressure.  Altering the temp of the oil is the best and main factor in reducing viscosity (but I am sure we all knew that)

Adding a few blobs of washing up oil made no difference to the viscosity either.

Girls and boys, don’t heat oil especially with petrol in it unless supervised by the fire brigade and St johns ambulance. 

No animal or human was hurt during these experiments.



Hope this helps someone

Well I had to pay £1.30 ltr today  :'( when is it going to stop.

On the plus side I did find water on our land today its not oil but still exciting all the same. All the test say its drinkable apart form the Coliform bacteria which needs 48 hrs to culture.

RAB,
Sorry I was being idle on typing your post name "Oliver90owner"  lol.

I am in Misty Derbyshire. I have a Lister CS 3hp and a Lister Petter genset (when I pick it up on friday)

I will put some old oil in a jam jar a bit of glycol and give it a good shake then leave it a month or two see what happens.  As a control I will just sit another jam jar full of untreated oil next to it.

If it cleans then I will look at the next stage of seeing what comes out the exhaust.  My freindly garrage will put  it on his emmisions meter.  We may as well gat true facts and figures rather than say dont do it. It becomes an informed choice then.

RAB, List
I was meaning the heavy metals etc.
If the particles are smaller than 1 micron would they cause any harm to the engine anyway.  Even if you have to do a rebuild every year, for me it would still be cost effective.  We pay about £100 per month on electric (its a farm not house) so the savings would be good for us.  Everything we have, where possible, is low energy. 

Oliver, could you expand on your glycol experiment please qty etc. your best guess would be fine.

Its nice to see and hear that people are willing to try and experiment on this forum rather than just tell you not to do it or go look for the answers that’s been posted 5 years ago.  When we have worked this one out we can start on what to do with the tyre mountain.  lol

Thanks Cognos,
Does anyone other than rbodell  just settle, filter the oil to 1 micron then run it in a Lister. 
Sticking a couple of large Neo magnets in the filter will pull some of the metal out (maybe) not non ferrous though.

There is much more WMO out there than Veg and if there is a safe way to remove the nasties from the exhaust gases say maybe use a cat? Then it’s a much better way to go.  We can put the veg in the car and provide electricity with the WMO

Just my 2p worth or 2c

I run waste veg through 3 filters
1, pillow case to catch the chip crud
2, 20 micron sock filter
3, 1 micron sock filter

All three are stuffed inside each other.  I dont heat (very often only when very cold) or de water or check PH.  I run my veg in an unaltered Landrover Freelander TD4 Common Rail engine.  I run at 30% winter and 40% summer (wvo) I have completed 10k+ with no change in performance or starting.  I just keep things clean and simple and have changed my fuel filter once about 7K.

I am not saying this has or has not damaged my engine ir pump??  This is what I am doing.  I would like to find someone close with a centrifuge to see if any more crud would come out.

on most diesel engines the pump delivers far more derv than is needed by the injectors so there is always fuel there for acceleration i  suppose.  On slow speed engines it looks like whats needed is whats used.  It is worth having the injector calibrated every year or so.  I had mine done for £15 it made starting very easy.

Thanks for the diagram

« on: May 26, 2008, 07:38:30 PM »
Well I have just bought a Lister 1.5kw genset on Fleebay, so short / medium term I can just run my new lister straight off.  It also has electric start as a bonus.  Its not a Startomatic more a Petter engine (I think).  I got it at the right price so as long as the Alternator is OK I am now sorted.
I got the wiring set up more permanent today. I have upgraded the line to 35mm2 cable so its now above the leccy recommendations of 25mm2.  Its bloody heavy cable though and not easy to form into neat runs, more pipe bending territory

Thanks for the advice guys / Girls.

Engines / Injector return pipe
« on: May 26, 2008, 01:08:38 PM »
My Lister CS 3hp has what looks like a return pipe from the injector blocked off. Is this a usual mod?  I would have thought it would put the injector under a little strain.

Thoughts anyone!!

This may come as such a daft question but I dont know the answer. :-[

use a cotton or hemp rope to siphon the oil out of the drum and into a gallon milk container or similar, the oil will be quite clean as cotton filters well.

Can Someone tell me how this work, I cannot picture sucking on the end of a hemp rope.  Does the rope just absorb the oil and slowly drip.  Therefore dangle one end in a bucket of oil and the other over the side.  If so what happens to the rope when it touches the lip of the bucket??

Thanks In advance.
