MG Midget and Sprite Technical - '64 Midget Solenoid connections?

I need some help please. Does anyone have details of which wires are attached to where on a solenoid fitted to a '64 midget? At the moment when I switch the ignition on to start the engine nothing happens. The solenoid doesn't engage.
Thanks

You need to turn the key against the spring to operate the solenoid; then you'll have 12v on the white/red wire between the two main terminals.

If this wire has 12v, then you should also have 12v on the starter-motor post; this should supply 12v and many amps to the SM itself.

If not, the solenoid is at fault (assuming there's 12v on the battery/alternator post...)

Hi Anthony,
When I turn the key against the spring I have power to the white/red. However this does not enagage the solenoid. If I press the button on the starter then the engine turns over. This isn't happening on the key though.
So close to start up.

This says the solenoid is faulty... assuming the body of the solenoid is earthed (is it?).

Another possibility:
Is the red/wite attached to the right terminal? If it is a replacement solenoid it may have a second small lug for a ballast resistor.

Have tried a solenoid from a 1500 and hey presto, it works. My problem is solved. Thanks all.
