[hypoxia]

Newell refers to the other one as a "KLAXON" relay (not positive of its function) and we replaced that one as well.

I think Newell was referring to the Sensata Technologies Klixon Series of circuit breakers.  Klixon is a quality brand circuit breaker which is used in the aircraft industry as well as others.  I have some in my airplane parts bag.  I'm wondering what the Buss Hi-Amp protects and if they have had problems with it.  There were 6 of them in my last coach and I think I replaced one in 7 years.  I foolishly left my spare Buss Hi-Amp breakers in my shop.
