Ruby ignition switch problem

[Dave Wortley]

I have a friend who has the following problem with his Ruby. The dynamo is putting out a charge but the ignition warning light is not going out and furthermore on switching off the ignition the engine continues to run and can only be stopped by putting the car in gear and stalling the engine. Needless to say the car is not and has not been used on the road for a while. It sounds like a faulty switch to me but perhaps someone has experienced a similar problem?
All replies gratefully received!
Dave.
