Has anyone figured out the fix to this problem. I am experiencing the same problem.

This is a quote from the MSD tech forum:
"Assuming that the carbon button was not damaged in transit, the only thing that I can see that would cause the carbon bushing to prematurely wear would be if the rotor tab was not making firm contact with it. If the energy was arcing from the bushing to the tab this will cause the carbon to wear away quickly. Upon installation of a new rotor (in any installation) we do recommend verifying that the tab is making firm contact. One way to do this is to apply a small dab of dielectric grease to the tab, set the cap on as if it was installed, remove the cap and look at the impression in the grease. You should have an indention down to the metal, if not you may need to bend the tab up slightly in order to get the proper tension on the tab.

The post is not a servicable item, there is no replacement part for it."

A chevy cap is interchangeable - I can't recall if it is from a big block or small block, but it is much cheaper. Black, too.

I was also told that if you use the MSD cap with the George Jetson looking tower they last longer.

Good grounds are always important.

Have you made sure your rotor tab is making good contact with the cap. Like I mentioned in my other post, mine was burning up because the rotor wasn't bent up high enough to make good contact with the cap. I have about 13k miles on the same cap now.

This post reminded me to check my rotor and cap - just ordered a new cap and rotor from Summit. Actually, from the looks of the cap I'm surprised it ran at all.

You need to check the rotor phasing. MSD had some of their spark boxes wired backwards. Also note that the phasing of a MSD 6-AL and a Digital six are opposites.

Tom,
I'm not sure I know what you mean. I have the MSD Pro-Billet dist and 6AL box. What am I looking for?

Thanks.
