I have a 94 K1500 and its been starting normally until today it cranked a couple times and stopped, after a few tries it wouldnt crank. Thought it was battery, starter, alt problem. I got a jump but it took a bit for it to crank enough to start. So I assumed it was battery. After getting home I shut it off and retarted it and it started normally. I went ahead and put a charge on it for a couple hours. From the time it started to charge the charge indicator showed it didnt need charged. After charging it started but it took several extra cranks, seemed weak. Replaced Battery, starter new within 12 months. At that time the truck sat a few weeks and battery just died, though its sat before and had no problems. Anyway, there is a new rattle sound coming from alternator area of motor. A metal, rattly tingy sound that comes and goes. I am wondering if the alternator is draining the battery or may have a bad connection at starter, alternator, though everything looked clean and solid.
I havent done anything with it yet, but wanted a suggestion on where to start(no pun intended).
I was going to take it to Autozone to test the battery/alt with jumper cables in tow.
Any suggestions will help.
Thank you
