Thomas>> When you scope the voltage at the input side of the choke

what the choke wants - it isn't conducting.
Now you have the inductor drawing current that
the diode isn't supplying so then you get the
lowering of the choke's supply side voltage.
The choke is sucking every available electron from
the wire and causing a voltage spike which only
discourages the diode from conducting all the more.DanL
