Hi guys I've hit a massive rock and an confused lol

Last night I started up the saff and let it run for 10 mins or so before I drive it, as driving up my road I noticed the rev gauge and fuel and the temp gauge was all on the bottom ( not working )
Battery light came on ect run like poo,

I'm guessing the alternator has lost its balls and given up it has a new battery on too,

I've taken leads off batt and left for 10 mins to see if that cured and now doesn't turn over fast enought like batt is flat.

If anyone can help would be great ful cheers
