| Sounds like a daft question but are there any problems running dynamo without any output connections? |

You'll probably struggle to charge the battery unless you're driving around the with a long extension lead!
More seriously, I don't think that there are. Remembering my physics A-level, a current is induced in a wire when there is relative motion between the wire and a line of magnetic flux. I think I'm right in saying that the lines of flux in these types of dynamos are provided thanks to an electro-magnet (the stator windings).
However, for a current to actually flow, there has to be a complete circuit. If the terminals aren't connected, there's no complete circuit, so no current flows. Perfectly safe, as far as I can reason.
Besides, I've been running without my dynamo wired up for 500 miles and it all tests out fine (long story...)
I hope this helps (and it's correct!)

Hi Paul,
Thanks for your confirmation. I am close to running the engine after rebuild and wanted to turn it all over off the battery without anything else connected up.

Tom,
Great stuff! I don't mean to sound patronising, but you must ensure that the oilways are primed before starting it up. I normally do this by removing the sparkplugs and carnking it by hand until oil comes from the tap for the dashboard gauge. Then I close this tap off and crank it a whole load more. You can't be too careful!
Best of luck and let us all know how it goes
