BTW, use clip on heatsinks when soldering wire connections and particularly coils in general.
Clean the lug holes and get a good wrap hook with the wires through the holes.
It prevents damage to the windings, lugs, and diodes and makes soldering faster and easier.
Wondering why a coil locks on, will not hold power, does not work or burning up a new coil diodes will make you upset and you will have to do work all over again...
