I've tried it with the drill, but my voltage readings are very low, about 0.5 volts at what I'd approximate to be about 1500 rpm. It isn't lighting up any bulbs.
I've cleaned the commutator which was a bit grubby, but otherwise to my untrained eye I can't see anything obviously wrong and there's no smell of burnt electrics or anything.
I'm a bit confused that it would motor quite happily but isn't showing any significant output. As the car didn't go anywhere for a year or so is it possible that it's lost some magnetism? I could increase the spinning speed or try measuring for longer in case it wakes up, but I don't want to damage anything by running it disconnected.
