I have a 2012 traverse that went into battery saving mode. Tested battery and tested good for 200 cranking amps. Tested alternator and with all meter and it tested bad. I wanted to test the fuse for alternator before I changed it out, however I can not find it! So if someone could point out where it is, I’d appreciate it. Also anything else you would check before replacing alternator? Also one other thing. It has been doing this for a while, with ac blowing full blast it weaken almost to shut off when pressing gas then come right back.
