This brings up a point I need to check with Roger L.: the sservice manual says "Connect a decade
resistace box across R11 (the 1.8K in most modules) and determine what shunt resistance is
required to establish the threshold of regeneration."

What is NOT said is are we trying to *start* regeneration, or *prevent* regeneration!!?!
