I can't get any readings between the secondary and primary or core
laminations on either leading or trailing coils. Is there a spark gap

on the

other side of the primary in side the coils?  On the leading coil it

seems to

me that one side of the secondary is connected to L1 and the other to

L2 and

the circuit is completed from coil L1 to spark plug L1 to engine block

to

spark plug L2 to coil L2. On the trailing coil secondary I cant find

how the

circuit is completed?

That's what I saw also, thought it very strange.  That also says the
schematic I sent last week has an error in it in the coil
primary/secondary.
I had "assumed" the two leading plug ports on the coil were the same
electrical node, but they're not.  There is also a white dot on one port

for the front plug.  I had thought you could interchange the leadings,
but maybe not, haven't tried it.

It's apparently not wired the way coils usually are.  Maybe Tracy can
clarify this.  I haven't looked a trailing coil yet.
