Hi bsafe.
These photos are from several years of Garbogen construction. They are not all from the same machine.
The 4 stock wires are conected to the seperate rectifiers in the 24 volt version.
For 12 volt use a sires-perelell configuration works best. As far as the aluminumwire is concerned, yes its a pain in the %$#^%& to work with. Thats another good reason to find a 1 hp. Very hard to find though.
If you've broken a wire short just pull enough slack or remove half a turn and redo.
I generally pull the wires to the outside of the coils to make conections. The wire pulls through the gaps between coils fairly easy.
You do have to scrape the wire gently. Aluminum is very soft. I twist the aluminum wire with the fine stranded copper hookup wire and use a crimp conector. Try to twist the stranded copper wire all the way around the aluminum so the copper makes barier between the aluminumand the sharp edge of the crimp conector. I normaly slip very small as I can heat shrink tubing onto the bear aluminum wire for pretection and firmness.
After all conection are made I go nuts with wire zip ties and secure all lose wires.
You can't tell the copper from the aluminum till you scrape the varnish off.
To do the sires-peralell wireing you end up with a total 8 lose wire ends. 4 for the runs and 4 for the starts. I make the peralell conection inside the can. You can extend all the leads and make your conections outside the can.
Befor reasembling the stator back into the can just conect the 2 wires for the run winding groups to a 9 volt battery. Then take a small ceramic magnet and hold near each pole. Going around inside the stator you should feel. Atract, repel, atract repel.
If it all atracts or all replells you need to reverse the leads between the 2 sets of run windings. Do the same for the start windings.
PS on that wire that broke. just pull it to the other side and add a jumper to get it back were it was. Thats much easyer the redoing all the other wires, that would put them at risk for breakage also.
Good luck and keep the questions comming.
What are you using for magnets, armature, blades and such?
