Okay, last night I decided to finally swap out my AQ2200 for my SAZ-3000. Like always I just disconnected the positive battery terminal and changed them over, when i went to put the terminal back on the battery I found out that the terminal wasn't getting a good connection so I swapped terminals. After about a hour I finally got it swapped everything hooked up, but as soon as I connected the battery the ANL fuse blew. The ground and all was good before, what could cause this?
Its a 2003 Ford Explorer if that helps, and it did arc a good bit while trying to fit the new terminal on the post. The fuse was a 300amp. Thank you.
