I have a 2017 SS Been parked in the garage on a battery maintainer for the last 5mos. Was fine when I parked it. I had started it and moved it around once or twice. Went to pull it out and it barely started (low bat?) The battery maintainer showed the battery as good (green) Well, it looked like the orig battery, so I went and got a new one (250.00) The battery was hard to get out due to the weight and the location. I replaced it and none of the electronics were working so hmmm, took a look at the fuse block assy on the bat and noticed Oh No! I ruined it dragging the battery over it/around it/by it. So I got another one (150.00) I installed that and it STILL isn't working, I thought there was more sparking than there should have been when I was attaching the cables. I checked the continuity on the 350A terminal it was 0. I'm guessing the 2nd fuse block is ruined. I have no idea what could be causing this, I'm baffled and I really don't want to keep throwing money out the window. Has anybody run into this? Any help is appreciated.
