The one in the picture I don't know how old it was, I bought our coach in 2019, it had brand new house batteries, the start batteries I changed this Summer and after reading about the merge relay here, decided to investigate our merge system. In merge the bus voltage was different at the house batteries than the start batteries at the battery terminals. So I was working the charging system outwards, when the merge relay came to play. Realizing of course that length of wires, quality of grounds and battery condition that no coach will be perfect match as to voltages. There was a difference in voltage on either side of the merge relay. It needed to come out. The relay in the picture I cut open maybe circa 1995, I don't know. The outside and inside of the can metal reflects a lot of time even with our coach being stored indoors. I thought I'd post the pictures, might help others.
