The wires from the rotor/stator assembly come from the left side of the
engine case. They offtimes get pinched, stretched, or broken. This
happened to my bike, and basically caused the TCI to go to hell as well.
Here's the fault-finding diagrams...:

If it's not this, it may well be the TCI that's giving you fits. I believe
you said you had two TCIs-one from the old engine, one from the newer. Have
you tried with both, yet? (Stupid question, I'm sure-just don't want to
overlook the obvious.)

I did a visual check of the wires and cleaned them up at the connector. I
got a
bit of voltage on some of the contacts, but without knowing what the
readings
are supposed to be, I couldn't tell if this was an accurate test or not.
Tomorrow I may remove the outer wire casing. I'm trying to avoid removing
the
right side of the case as I don't want to have to drain the oil. But if I
have
to I will.
I know it's something simple, but finding it is going to be a bear!
Thanks again,
Barry
