Harry hall Posted April 17, 2020 Share Posted April 17, 2020 Hi There, recently acquired this large diesel generator. Managed to get it to start BUT only if I operate the injector pump myself manually. There is something stopping g the engine governing and idaling on it's own. The actuator arm doesn't move by its self al though isn't seized as I can moove it manually. Can anyone point me in the right direction? Or have any documents for this beast? Thanks Harry Quote Link to comment Share on other sites More sharing options...
mogmaner Posted April 17, 2020 Share Posted April 17, 2020 Check the flywheel sensor is clean , these pick up metal particles from the ring gear over time, when refitting tuck on to the ring gear lightly the back off 1.5 turns ,connect a meter across the the sensor on A.C. then spin the engine over .you should get 5v or more pulses. This is fed to the governor as a reference for speed control .if you find the model of governor I may have some paper work . Hope this helps.

Would this stop the engine from starting? I have attached photos below. Many thanks Quote Link to comment Share on other sites More sharing options...
mogmaner Posted April 17, 2020 Share Posted April 17, 2020 Later units go into lock out if there is no signal from the flywheel ,main things to check is battery volts to the unit then the sensor .if these are ok you may have a board or actuator fault, bad connections and flywheel signal are the most common cause of starting problems .

Hi Again! Done as you instructed, im not getting any current out of the sensor, tried ajusting still no luck! I guess now is the time to try and source a new sensor and go from there. Fingers crossed it works. Thanks for your help so far! Quote Link to comment Share on other sites More sharing options...

john1950 Posted April 20, 2020 Share Posted April 20, 2020 Have you any dry electrical spray it may just be the connector pins not contacting. Quote Link to comment Share on other sites More sharing options...
attleej Posted April 20, 2020 Share Posted April 20, 2020 It should be easy enough to test once you know how it works (probably reluctance). Try googling the part number on it or find the NATO stock number from a parts list. It is conceivable that I might have a microfische. Mogmaner appears to be on the ball with this one!

John Hi John, I've had it tested now by someone with a bit more experience than me! He's prety sure it's not working! Have tried Googleing the part number but no luckk. But have found some generic sensors for generators. the same size and with the same thread. Hopefully one of these may fit?

MatchFuzee Posted April 20, 2020 Share Posted April 20, 2020 Newton Derby maybe able to help you with the sensor. Grangefield House Richardshaw Road Pudsey, Leeds LS28 6QS Call us.

mogmaner Posted April 20, 2020 Share Posted April 20, 2020 Back in work shop tomorrow will look in my junk box. They work on magnetic induction ,as the ring gear teeth pass the sender they induce a AC voltage which is fed to the controller, as the speed goes up or down its conspired to the set reference for up or down adjustment to the speed.send me PM so I can let you know what I find.

Harry hall Posted April 25, 2020 Author Share Posted April 25, 2020 Still havnt managed to fix this! Tried a new sensor still no luck! Any one with any information who can help would be brilliant. I'm prepared to pay someone who is capable of fixing it for met to come take a look Quote Link to comment Share on other sites More sharing options...

john1950 Posted April 26, 2020 Share Posted April 26, 2020 Have you run it manualy to see if the generator is working generating the designed output. Quote Link to comment Share on other sites More sharing options...
Nearly Posted October 6, 2023 Share Posted October 6, 2023 (edited) Hi, just agreed to buy one of these genny's with the opposite problem to OP. The engine starts and runs well but there's no output. I'm close enough to Leeds to pick their brains and local genny sparky is onside to learn too. Thanks all, Neil Edited October 6, 2023 by Nearly Quote Link to comment Share on other sites More sharing options...
mattg Posted December 17, 2023 Share Posted December 17, 2023 How did you get on Harry and Nearly? Did you manage to get them going? Did you ever find any useful documentation for them? I'm going to look at one soon, trying to learn more about them in advance. Thanks Matt Quote Link to comment Share on other sites More sharing options...
Nearly Posted December 17, 2023 Share Posted December 17, 2023 Not had chance to pick it up yet. The owner called the company in Leeds who were very chatty about them. 'Yes, that's one of ours etc, but unfortunately we can't tell you anything about it as the design is covered by the official secrets act' This may be an exaggeration but they weren't able to help. Surely it's no secret that if you rotate a wire inside a magnetic field the electrons run around. Quote Link to comment Share on other sites More sharing options...

fv1609 Posted December 17, 2023 Share Posted December 17, 2023 I see I have got listed the FAESP 6115-H-500-821 Generator Set, 16/24 KW (Newton Derby) Gen. Instr & Index. Not sure if I have more on it, will look later. Quote Link to comment Share on other sites More sharing options...
mattg Posted December 17, 2023 Share Posted December 17, 2023 Hi FV1609, if you get a chance to look them out I would be very interested to read them! Cheers Matt Quote Link to comment Share on other sites More sharing options...
attleej Posted December 17, 2023 Share Posted December 17, 2023 I hate people who lie and claim that legislation prevents them from helping. These machines appear to be made 40 years ago! If our opponents wanted to, they could buy one S/H and reverse engineer it. There may be some secrets about reducing the electromagnetic signature or why it has to be so complex but they are not relevant to what we need to know. I wonder if the actual alternator is rather simpler than we might think. Normally, it is a rotating field coil and a stationary armature that supplies the output. The military version will have all sorts of facilities such as being able to parallel machines and, no doubt, tight frequency control with complex systems to achieve this. Could we / you not bin the complex military system and take a modern commercial voltage regulator and fit that instead? John Quote Link to comment Share on other sites More sharing options...
fv1609 Posted December 17, 2023 Share Posted December 17, 2023 I had a few more FAESP than I thought & one does list Associated Publications which will give you a shopping list although some of those are in fairly general terms. These are the pages in the fiche that contain info: 28 pages Purpose & Planning, Operating Instructions 56 pages Failure Diagnosis & Repairs 12 pages General Instructions There are 12 pages of Maintenance Schedule but this is for the Hunting CL version. I can photo the odd page but it is too time consuming to do more. I'm not sure at the moment whether I want to break up my series of fiche on generators. 1 Quote Link to comment Share on other sites More sharing options...
