Just got my 250amp alternator with big 3 upgrade to 0ga done. I noticed that when I shut the truck off I can hear the battery making kinda a fizzing sound...... battery doesn't feel hot but I can hear it coming from the lil foam holes on top of my red top optima.... should it be doing this?

If the dealer did the work. I'd bring it in and show them. If they say it's fine, then later if it's not, you've got something to go back on them with.
