There are a few views on this, so I'll post a quick update.
Apologies for the numerous pictures, but they tell the story ....sort of.
As I said, the motor is quite good, and after a bit of a clean up, some new fuel gaskets and a magneto adjustment, it runs well.
The power side though, is not currently working.
When running, and selected to 240 volts, the volts read 25 volts AC approx, with no frequency or load. This is with the 'Mains' switch On and all of the socket switches off.
When one of the sockets is switched on, the volts drop to zero, the frequency meter just reads on the lower left side and the load comes up to about 10%.
It did work normally once with correct volts and frequency, but when one of the sockets was selected on, the fault came back.
So I know that it does work, well it did once.
I checked the cable between the generator and the control box, it was fine.
All the switches work according to my multimeter.
I've had a look in the control box,
Back of control panel,
Interior of control box
It all looks okay, no loose or burnt wiring, no water damage,
No obvious burnt or cactus components,
Complicated but looks fixable....
I removed the generator end cover,
This panel had quite a bit of white powdery corrosion, sorry no before pic.
I carefully cleaned it up, looks a lot better than it did.
A bit hard to see, but the transistor (if thats what it is) and 2 of these terminals are insulated from the plate with small plastic (mica?)washers so that they are insulated from the other 2 terminals. This was where the corrosion was, possibly grounding the insulated terminals. The wires also have an insulating ring to stop them touching the plate where they go through it.
Unfortunately, cleaning up the corrosion didn't help, still the same lack of output.
The brushes don't look too bad,
A bit out of my depth at the moment, I have contacted the RAEME museum and they will ask around to see if they can come up with a wiring diagram or any manuals etc. for this thing.
If any of this jogs anyone's memory or if any one knows of any parts for one of these lying around, I'd be very grateful, It would be terrific to get this up and running again.
Cheers,
Mike.
