What's up everyone, I'm new to the forum as well as a new tacoma owner. A couple days ago I turned the key and got the click, click click noise. I have a battery charger and have been charging it, to the point where it starts normally. I'll drive it say for 15 minutes, and when I start it again it's either dead, or has a hard time. I checked the 80A alternator fuse and it is still good. I was wondering if there is an easy way to check to see if my alternator is bad. I heard you can take the ground off the battery when the truck is running, but that it may fry components. I just don't want to get a new battery or alternator if I don't have to, and don't want to get ripped off from some mechanic.

Thanks alot for any help! I appreciate it.
