Thanks for the suggestion but unfortunately that will not work in my case.

I had already thought about doing what you suggest and simulated it by
momentarily, like for a split second, disconnecting the pilot within
the EVSE while plugged into the Leaf. The result is that the Leaf
still goes through this "testing" cycle where it requests a momentary
charge. The Leaf does this cycle every time it is plugged in or in
this case when the pilot returns. Creating the circuit that you
mention would just end up having the EVSE and the Leaf in an infinite
loop.

In the end I guess what I am looking for is a replacement pilot
generator that I can use in this EVSE or a way to hack the EVSE in
such a way that removes the disabling of the pilot after a cycle. I
am fairly good with tools and electronics and I am willing to
disassemble this EVSE for further exploration since with its current
limitation it is not much good for using with the Leaf. I can get by
with just L1 charging with the Leaf for now but if I don't find a
solution for this EVSE soon I will probably purchase a different EVSE
and offer this one for sale.
