So... my buddy hooked up his battery tender backwards and now no power , he checked the fuses and all check out good. still no power to dash or starter??? Any ideas?

I thought most battery tenders are intelligent and will not work with reverse polarity. I now my cheap Canadian tire one is. Tell him make sure his kill switch is up lol.
