That is an AC stator and requires the 691185 regulator. Cutting a wire should had killed it as the windings are normal not grounded unless there is a defect in the stators. but of course the ones I referring to are full circle stator and not a half circle ones.
So something just don't sound right.
Also there a MS sheet that might need applying as there is possible shorting issue.
