Thanks for the continued assistance. I studied that Delco Remy manual and now understand how these things are supposed to work. I am an electrical engineer so I think I got it. I will try to bench check it myself this weekend, but if I am still stumped I will send one. I will also check the residual voltage per your suggested test. Following the schematic, it looks like the field terminal starts off grounded through both the voltage and current regulator contacts. Since I already know the generator charges with the field terminal is grounded directly, one or the other of those contacts is opening. Or something I assume is grounded - isn't...
