I am having trouble keeping a charge in the battery in the truck. It's a '94 K1500 350 with a less than 2 year old Auto Zone Duralast battery.
It's no longer the daily driver (thank god, it's 50 miles each way[img]/wwwthreads_images/icons/crazy.gif[/img]). We had one cold week right around Christmas and the truck sat for about 3 maybe 4 weeks during this time. When I went to start it....nothing. I couldn't even jump it.
Took the battery to Auto Zone to get it tested. They had to charge it before they could even test it (frozen battery???). I came back in about an hour and they tested it, it checked out OK. Took it home, put it in the truck, everthing's cool.
Later, it sat again for another couple of weeks and needed to be jumped. This time I could jump it with no problem. Drove it about a 10 mile round trip to the store. It sits for 3 days this time, and I needed to jump it again[img]/wwwthreads_images/icons/mad.gif[/img]).
Here's the kick in the pants... I decided to take it to work last night. It starts fine. I drive the 50 miles to work (still daylight, no headlights on). Go to lunch (after dark), no starting problem. Get a call to go to another building (about 3 am) Starts a little sluggish, but not too bad. Leave work (6 am) Starts, but just barely. Stop at the end of the 50 mile return trip to pick up a 12 pack (hey, it's Friday for me[img]/wwwthreads_images/icons/tongue.gif[/img]). Shut the truck off, spend 3 minutes in the store, come out and it won't turn over fast enough to start[img]/wwwthreads_images/icons/crazy.gif[/img][img]/wwwthreads_images/icons/mad.gif[/img][img]/wwwthreads_images/icons/crazy.gif[/img].
Should I get the alternator tested as the next step?
Is there a short or a drain on the battery somewhere?
Is the battery really OK, just 'cuz Auto Zone said so?
Please help me figure out where to start.
