92 Regal Need Help!!!

I have a 92 buick regal GS not supercharged 3.8L. I jus put a new battery in it and it started right up no problems...then i tried to start it again and it wouldn't start. It sounded like it lost power when it was trying to turn over. Is something draining my battery?

This could be the starter, or corroded positive or negative battery cables.

Notice on the positive side, there are two large cables mounted piggyback with a spacer in between. Remove the rubber insulation to expose both cables and the spacer, and then check for corrosion between the two sides. In addition, look at the cables to see if you have corrosion inside the wire. If you find any corrosion, use a 50-50 mix of water and sodium bicarbonate (baking soda) with a brass brush to clean everything and then apply dielectric grease on all sides before reassembly. If the wire (cable) appears corroded, you may need to cut back the cable until you see clean wiring inside & install new terminals.
After cleaning & tightening the terminals, take the car to AutoZone or Advanced, and have them do a battery load test and alternator output test, then post back.

Thanks man your a life saver. I cleaned up the cables and reassembled them, and it worked. started right up and kepped the voltage. Thanks again
