Bob,
Good-Oh!
Does it have a heat sink?

If so please take a picture.

The fundamental problem is a one rotor fires once per revolution
and has one main coil while the equivalent two cylinder four
stroke piston engine has two main coils that fire every other
revolution. That means a rotary running at 6000 RPM continuously
is equivalent, as far as the coils are concerned, to a four stroke
piston engine engine running at 12,000 RPM continuously. It is
amazing the Denso LS1 coils are as durable as they are.

 From this you can see the problem. We need a bench set up so
we can test coils for heat rise while firing  at a continuous
6000 times a minute. Perhaps we should contact MSD and see if
they have something.

Seem like the old 2nd gen coils were more reliable.

Paul Lamar ...No rotor no motor.

Hi Paul,

I sent the D585 photos out this morning but now I see that I grabbed the
wrong pictures. Here are the correct ones.

Bob,
Thanks - as usual!

If anybody gets a failed coil please send it to me.
I'll try to dissolve the potting compound in MEK or something
like that and see what is in there.
