I searched the term relay and read through 11 pages of post to see if this was covered. I could not find it. As a lot of you are aware the coach i bought had been broken into and as much of the wiring they could get their hands on had been stolen. I have completely rewired the underside of the coach and all systems work as far as i can tell. Only issue i found after rebuilding the underside power panel is I don't know what this relay and circuit breaker is for.  Marked in picture with white arrows.
