Ok, so I just had two new batteries installed in my 97. (I wasn't about to mess around with my truck in -10 degree weather.) And on my way home from a 6 hour trip my battery light came on and my battery gauge was dipping to almost nothing. Before I knew it I had no lights or anit-lock brakes. I pulled over to check the battery connections. Sure enough my passenger side battery terminals were loose.
I tightened them up and jump started the truck. I then took it straight to my grandparents house thankfully 10 minutes away and charged the battery. Well, after it was charged I made it about 20 minutes before the same thing happened. This time I installed one new battery into the passenger side. This allowed me to continue for 2 hours towards home. I got home, but now my battery light is on again, and it's only a matter of time.
So, now the questions:
1. Should I start completely new and put in two new batteries that are for sure good? Would having my passenger side battery charged and my drivers side one dead give me the result I got. (few hours of driving but eventually dead.)
2. Or, should I expect that my Alternator is shot and replace it. Would Autozone be able to check my alternator without pulling it out and without two fully charged batteries?
3. Is there some other electrical problem that is messing up my truck?
Sorry this is so long, but there is no way to tell you smart guys everything in just a few words. All suggestions will be much appreciated
Thanks Guys!!! -Scott
