Trying to troubleshoot some problems with my truck

Asked by Ivos Feb 12, 2018 at 10:12 PM about the 2002 GMC Sierra 1500 SLT Extended Cab SB

Question type: Maintenance & Repair

Okay, so today I gave my truck a boost, cause the battery was plum dead. So I checked the terminals the
negative was a little loose, I’ve tightened it since then (before giving the truck a boost that is) but now the
thing is, I’m thinking my alternator is bad maybe. Even though I didn’t thoroughly check my ground wires. I’m
to sure what they may be, any advice anyone?
