I’m seeing intermittent lockouts on electrified mortise cases (Sargent/Corbin) where the solenoid spikes to about 320 mA and the latch monitor misreports, and I want a course that teaches deeper diagnostics with a clamp meter and scope, not just installs. Prefer a hands-on weekend class within 2–3 hours of Chicago — what programs moved the needle for your repair reliability?
When I chased a ‘320 mA’ spike on Sargent mortises, the fix was verifying coil suppression at the lock — clamp meter in inrush, scope across the coil, then add a flyback diode at the body instead of relying on panel-side MOV; it stopped the latch monitor chatter. For a nearby weekend hands-on, IDN‑Hoffman in Bensenville often hosts a Saturday electrified hardware troubleshooting lab that really sharpened my clamp/scope workflow. What power supply are you feeding those from?
