Thanks Bob,
Sorry to hear you were affected by the bush fires.
I've attached a photo of the circuit diagram.
I'm off work after today, so I'll do some more investigating. Thanks for the warning about the condenser. I had spotted that on the circuit diagram (it says 400V DC on mine). How long will it hold its charge?
Cheers,
Sean

Hi Bob,

Thanks for getting back to me. The picture of your control box was one of the ones I was admiring when researching solutions.
I've heard about the selenium rectifiers issue. I can't see anything that looks like one (cooling fins etc). The the alternator box and generator head have some big electrical component where I'd imagine them to be, but I don't know what they are.
There is a scattering of diodes in the control box (see original picture). 'D' has obviously been replaced by a modern relay. And there's an additional large component in the bottom right, again which I'm unsure about.
When I had the fuel solenoid apart I checked the points below the top cap, which seem fine.
Would it be worth, at least partially, starting again, using modern rectifiers (as you've described previously), making a better job with the diodes etc and generally tidying things up? Would it be worth returning 'D' to an original if I can source one? All advice gratefully received.

Sean

Hi, I'm a newbie to this site, but have been struck by the collective expertise on show.

I live off-grid in a small 1830 cottage on the Isle of Man. I have recently bought an SR2 6KW statomatic generator, with the intention for it to be a back-up power supply when renewables fail me. However, I need power to build the infrastructure to house everything, so until then it is my only source of electricity. Or it would be if it worked!

The engine starts easily by hand or by the start button on the control box. However, as soon as the lock on the throttle is removed (for hand-start) or if the start button is no longer pressed, the engine dies. The decompressor solenoid is working. The generator generates AC power when running. So the problem is with the electronic throttle control.

The mechanics of the throttle are free and in good order. I have had the throttle solenoid apart and that looks OK. Have tested both coils and the resistance is correct for the gauge of wire and number of turns, and it clearly works with the push button start. So I guess it must be in the control box.

I have attached photos. You can see someone has done quite a bit of messing at some point. It bares a resemblance to the circuit diagram and photos of other control boxes on this forum, but there are extra bits!

Any pointers gratefully received. Until that point I'm on headtorches and candles.

Thanks,  Sean
