I had an unresponsive pop to fix so I replaced a tip102 and a 2n4401.
When I turned the machine back on, I saw a little smoke, and had a new locked on left sling once again. Great.
Problem: When I try to cycle the machine through coil test, it goes from 1-16 and skips the special solenoids 17-21.
What could cause this?
