I have to ask, is that a noise suppression resistor in-between the contacts or is that something else? I've never seen a rotor that didn't have a one piece conductor, but I don't have many distributors left anymore.
I'm surprised the rotor didin't have to pass a continuity inspection and receive a verification mark before it went in the box. Those steps add to the cost of the parts, but it's minimal compared to the cost of selling a defective part.
Thanks for posting!
