Thanks all. Yeah it was pretty impressive in a bad way. So quick newbie question- should / can I test the starter before buying a new battery? Or do I start by popping a new battery in? My son and I double checked the connections and they seemed tight. We did lose the bolt that holds the clip...
Hey I had the positive terminal connector wire melt when I replaced it yesterday. 93 gmc 3500 diesel dually. Replaced both batteries. Happened after running it for twenty ish minutes shutting it off and trying to restart and hour later. Rig never moved.
