so I wrapped the stator with copper wire.. i now have to solder the wires to the wires preexisting that ran to the bike that i earlier had snipped/ How do i solder exactly? Do i need a soldering iron?? oI'm assuming I can't use my acetylene torch now when i solder the copper wire to the other copper , is it simply wire to wire with solder connecting them? or is ther some other 'attachment i use?? some wire crimp type deal?
