Peugeot 205 starter problems

[timolloyd]

My diesel 205 starts and runs fine, but on a couple of occasions there's been a whirring noise from the starter motor/starter solenoid while the engine is running.

The starter motor gets hot quite quickly and the noise doesn't stop when I turn off the ignition - I have to disconnect the battery to make the noise stop.

I'm guessing the starter motor isn't sticking on, because the car is running.

Any ideas where the noise is coming from?

Thanks for your suggestions. After further investigation earlier in the week I am ashamed to say it looks like nothing more than a loose connection where the (excitor?) cable connects with the alternator.
