Is this the factory solar controller?
I'm trying to figure out what this relay is in my recently acquired 2005 International 28. It appears to have solar panel wires connected to it (but also positive batt cables to both sides...??), and has a Cat 5 cable running to nowhere (the cable is cut).
Is this a charge regulator and was the Cat 5 cable originally to the display unit? Can I eliminate this if I install another regulator (thinking of an mppt like solar Boost 2000).
