Thanks for all the replies! I think going forward, my buddy is going to try and repair his unit utilizing parts from an old damaged KW I had received. The core from my unit looks pretty good, I'm sure my cousin wouldn't have bought it non working. That said, in 40ish years the cord is bad and that's why opened it to begin with. Assuming we have all the parts we need, well post back to the forum the rebuild. Based on what he runs, I don't know if we should worry about the breaker, at least swap from my unit. But adding a 10 amp resetting breaker in the line outside the unit couldn't hurt.
As for O Gauge Jim, Thanks, you may be needed!
