Thanks for the replies. I have to admit it was the "belts". We tighten them up and WALA, she keeps the cycles when a load is added.

I haven't looked "inside" yet which I would do if I didn't have a friend coming over Saturday who's a good diesel mechanic. He's also knowledgeable on generators so I think I'll just wait and have him take a look. I do have a "SL/LD 1,2 & 3"shop manual also a nice "ST range" manual with great pictures, that someone gave me years ago. I wonder how simaler the governors are in these small older Listers. I have also gotten some good advice on what to look for from "oldgoat". As to the problem of fluctuating volts AND cycles, what has been told to me by a couple folks here, is "both" fluctuating would point to engine RPM not holding steady. The belts aren't slipping which most likely means the governor is not governing. I did consult the kind folks over in the "generator" forum.

oldgoat, thanks for that. I'll get the manual and have a look where those components are found. If it's beyond my mechanical abilities, I have a friend that's good with engines. I must admit, although I retired from running boats, there was usually an engineer to deal with major problems. Thanks again, Steve

Engines / Lister SL2 governor?
« on: January 08, 2022, 11:55:54 PM »
My SL2 is belt driving a 5KW ST generator that wont hold cycles at 60. It doesn't fluctuate a lot. My belts could be a little tighter but I believe they are fine. I used some belt dressing and gave it a try, but no change so, as had been suggested, it might be a governor problem. I really cant hear any RPM change as I adjust the speed but it doesn't seem to take much to effect the cycles. When I run my SL1 with the "Northern" generator the cycles are nice and steady. Any help would be appreciated. Steve

Generators / Re: Light flicker vs Engine RPM
« on: December 29, 2021, 04:41:52 PM »You may have the voltage, but what are the Hz doing?
What kind of lights are you running? I would think incadescents wouldn't flicker. LEDs may need a seperate driver. Fluros are notorious for it, even on mains supply.
If I have it the right way round in my head, on my miller genset, you set Hz by RPM and voltage with a resistor to the control circuit.
Is the gen head de-coupled, can you change the pulley/drive ratio?
You could put capacitors across the output to smooth it.
The other thing (when we were wiring fluros in a 3 phase shop) was to run the lights on alternate phases so that they "overlap" and provide a reasonably constant illumination. Not sure how you'd go about that with your set up.
Mihit, Thanks for getting back, I appreciate your help but I'm afraid my knowledge is limited. The lights I use are mostly incandescent. The fluctuating cycles I understand would be caused by fluctuating engine RPM? My belts seem tight enough, but to test that I thought I'd use some "belt dressing" and if the cycles stay steady I will adjust the position of the generator. I would think if the engine RPM was fluctuating I'd be able the hear it, maybe not?? Anyway I cant seem to find my stick of belt dressing at the moment and the local Napa's "belt dressing" is to stop "squeaks" not give the belt a better grip. I certainly could be wrong about what belt dressing is suppose to do though.

Listeroid Engines / SL2 throttle lever
« on: December 27, 2021, 08:52:33 PM »
Greetings,
I have a Lister SL2 driving my 5KW, ST generator. The part that goes down the center of the throttle lever and meshes into the notches in the arc is buggered. I have had a jury rig set up for years and think it's about time to look into replacing the part if I can find one. Anyone have one? My other option is to take it to a machine shop. Looks like it's only held on with a couple bolts "underneath" and the linkage. Thanks in advance, Steve

« on: December 26, 2021, 11:39:09 PM »
Thanks for the replys.
broncodriver99, Not much of a load, a couple of freezers and friges, lights, small bathroom heater, TV. I think the engine RPM is steady. Wouldn't an RPM fluctuation in a two cylinder Lister be noticeable? I got my "ST" owner's manual out and I will open the "cover window", blow any crud out and clean the slip rings. I will do that as soon as the temp up here in the PNW comes up a little.
BruceM, I'll check the tension of the belts (2) when I open the cover window. I'm not sure I have enough knowledge to troubleshoot anything if I had an oscilloscope.
thanks much for the help guys, Steve

Generators / 5 KW "ST" acting up & down
« on: December 26, 2021, 08:37:48 PM »
Good Day,
It's been a while since I've been around as things have been working fine till now. When a power outage occurs I've been using my small one cylinder Lister and 2.9 KW gen set but today I needed more power and fired up the 2 cylinder Lister with the 5 KW, "ST" generator. I ran it for a couple hours and the voltage and cycles kept going up and down. Voltage from 109 to 125 and cycles 57 to 63. The volts and cycles would hold steady for several minutes then fluctuate again. This happened the last couple of times I fired up the "ST". I'm wondering what the "safe" perimeters for volts and cycles are but mainly what the problem might be and how to fix it with my limited knowledge. I've heard of a "automatic voltage regulator", is that what this generator needs? My cheap little"Northern" 2.9 generator works like a champ. Any help would be appreciated. Steve

Thank you very much for that information. I'll pass that on to the owner. You mentioned the water cooled exhaust manifold, I did notice that it was totally rusted out. I appreciate your help.

Yes, it would be nice to see it get put back into service but unfortunately I have no more room for broken engines. Hopefully the owner can find a new home for it up here in NW Washington state, lots of boats around here.

Engines / Lister ST"W" vs SL
« on: May 21, 2017, 06:39:48 PM »Greetings. I have a Lister SL1 and SL2 running gen sets and my question is, would a ST2 (raw water cooled) Lister be of any value as a "parts engine"?
The ST was in a friends boat and apparently running good as he used to crank start it then one cylinder quit firing and his mechanic thought it was a valve problem. He offered the engine to me after replacing it with a Kubota. So I'm wondering if its worth hauling away. Thoughts? Thanks, Steve

Engines / SL1 starting problem
« on: March 12, 2016, 09:40:24 PM »
Greetings, I have a Lister SL1, belt driving a 2,9 KW generator head. The engine was recently rebuilt when I got it a few years ago and has not seen much use supplying power when the grid goes down. It has always started right up. The fuel line devolved a leak and the engine wouldn't start so after fixing the leak I figured bleeding the injector pump would fix it. Fuel came out but Still no start so I cracked the high pressure line at the injector and had fuel squirting out around the threads when I cranked it over. (wife holding down the rocker) So what now? It looks fairly easy to pull the injector but I thought it a good idea to ask for some input before I go further. Should I try a shot of ether?
