Just for grins, Jeff 1.0 have you tried spice models of the rectifier
solenoid at 480 and 240? It may help you see something you may have
missed.


It hadn't occurred to me to do that. It's pretty much of a static
operation. You apply power, it pulls up on the armature. When the
mechanism changes position, an auxiliary switch disconnects the
solenoid.

BTW i expect you will replace the bridge with one appropriated
rated for the solenoid?


The original bridge was dealing with 480 vac @ 5.2 amps. The new
coil will present a load of about 4 amps @ 240 vac. It's not an
issue.
