Premium rotors?

Share this page

It may be that there is a flaw in some of the aftermarket rotors--but I still see NOTHING that indicates it has anything to do with the plastic. Look, the rotors are all made of the same material--so why don't ALL of them fail? If the plastic is conductive, why can't I measure any resistance in it? (It would have to be on the order of several megohms between the rotor and post, which is easily measurable. I measure infinite resistance on the 2 meg scale of my meter.)

For those of you who've had problems--how did you confirm that it really is a flaw in the rotor? Did you rule out, for example, that the contact radius in the cap is too large, and only rotors that are a bit oversized will work? There are all kinds of things that could go wrong that look like a bad rotor, but are really something else.

Finally, do we really know that the overpriced one does not have whatever flaw the other aftermarket ones have?

I'd still like to hear Moss explain why they are selling defective rotors, and why one that works should be absurdly expensive.
 
My best logic says that the brass rivet that holds the rotor arm to the body might be deep enough to make too small of a gap between the rotor and the top of the distributor shaft.

Perhaps the resistor-less coils pop off hotter and can make that circuit possible?
 
Since I have several cars and things easily get mixed up, I keep all my take-offs and spares in the trunks of my cars. My Sprite has two boxes full of potential replacement parts :wink: I think I have two caps, two rotors, and at least 8 plug wires. Overkill, but I'd rather just keep everything with the car rather than have it get lost in my garage.

Man some of you guys must drive around dragging trailer loads of parts! :driving:

I have a small (14"x6"x8"), soft sided, zippered top tool bag that carries a compact tool set and my spares, along with an owners manual. I transfer it regularly between the TR3 and the Midget since the tune-up parts are interchangable with the exception of the distributor lead.

Size of my parts cache is directly proportional to the expected distance of the trip. I have 2 soft sided bags that fit on the shelf behind the seats. One has jack and lug wrench. Other has fuel pump, oil and ignition spares. Tool box is a 4 x 5 x 8 inch. Just found out it was my brothers first tackle box when he was a kid.
