So I have a Hifonics BRZ 1700 that has been repaired.
When I look at a sine wave on the output and I gently twist the output inductor it seems to shift 180 degrees out of phase. When i let go it pops back.
Took inductor off the board but cannot find a short. Re-installed and same thing.
Any ideas?

Does the current draw from the 12v power supply increase/decrease when you twist the inductor?
Change the trigger level on the scope to see if it still seems to change phase.
