    Help identifying

    Hey all, been getting my new to me 2008 2500 long distance road-ready. I noticed this electronic device mounted to the passenger side battery tray. It looks like it’s been hot a time or two. What is it and would you consider replacing?

    The wire coming from the battery to the relay should be a fusible link.

    Looks like your grid heater element on the air intake is shorted to ground.

    Maybe the grid heater is sooted up real bad. Would that make it over heat and draw too much? Just thinking outloud here. Mines deleted and still starts fine below zero. I see you're from the North country though.
