Huge battery draw!

[ftf19]

Ok all, thanks for all the help! When I pulled the b+ cable off I got a 5 amp drop which brought me down to normal. So the picture show is the b+ wire right So I am guessing that the alternator is fried? And I am sure you all know the next question, is there a thread out there with the easiest way to replace the alternator? I watched a couple of videos seems like a pain but I hope this solves most the TCC problem, fingers crossed. Anyway thank you all so much and I will have plenty more noob questions for you all, hopefully some of you stay with me. Gonna change the alternator this weekend, stay tuned.
