David, 10amps is pushing it a bit. The harder the dynamo has to work the hotter it gets and asking too much from it can melt the commutator. Personally I would back it off, even if there is a discharge when you've got everything on. Try resetting the 3rd brush to tone down full output. With a fully charged 80Ah battery you could run lights on for 10 hours (theoretically) without anything going back in, so a slight discharge is OK. Changing to LEDs will further reduce the demand on the dynamo and allow you to back it off even further.
For your resistance wire it will be a matter of trial and error to find the length that reduces the summer setting to about 1amp, running. Once you've got the right length you can coil it up and just let it sit between the D & F connectors on the dyno.
You could remove the dust cover for a bit of extra cooling too.
