Hi Dave,

What do you mean that the solenoid has practically no coupling? 
Certainly it does. There is both electrical connectivity and mutual 
inductance between those two coils. They definitely couple to each other 
and probably a good value considering their proximity. Give me specs on 
the two coils and I'll tell you how much.

How did you measure coupling between the two?

Take care,
Bart
