Oh yes, I think 'capacitive coupling' rather than 'resistive short' would be my explanation. !!ESCAPE!!

I like a bit of "captive coupling" on the right day !OMFG! :cool:

Is that not just another name for 'marriage'?

By the way, I have absolutely no knowledge of the electrickery stuff, so am unable to provide constructive comment. My apologies to radiochrissie. I hope you find the part you need.

I think it is called 'bad luck' BP.
Could the insulation have split or chafed around the retaining clip perhaps? Switch it on and run your tongue along the wires. I'm sure if there is a fault you will soon find it. :!:
(Capacitive coupling wouldn't provide the power - the solenoid would soon drain it)

Good god, All I can taste now is metal, it certainly cleans your tongue up :!:
As I have said previously, my solenoid is no more, it has ceased to be, all I need is someone to help me find a replacement or give me the part number that is written on the coil sleeve. |/XX\|

Sega Windsor now fixed !
As I was not able to ascertain the correct solenoid I made my own :cool:
The original solenoid coil had gone short circuit due to overheating and measured just 0.4 ohms, to find out the correct resistance I carefully unwound the coil, which was 77 metres in length. I then measures the resistance which was approx 12 ohms.
The dropper resistor in the machine,which is in line with the solenoid coil, was measured at 24 ohms.
I now know the total resistance across the 30v supply is 36 ohms so using ohms law i know that the current in this circuit is 833 mA. Then using V=IxR I know that the voltage across the solenoid coil is 10v. So I then obtained some 26 swg enamelled copper wire and rewound the coil using approx 77 metres. When I measured the rewound coil it was about 11 ohms !SMARTY! Here is a picture of the new working coil.

Well I understood completely the whole of the

As for the rest, well done (whatever you did......)

and you did it all with the machine upside down !!IDEA!!

I beat you Aristo....I managed one and a half lines and the v= i x r bit from physics lessons 100 years ago. Well done Radiochrissie on a great result,enjoy.
