Just spent 200.00 on new battery, and oil change, they told me the alternator was really good.
The car starts sometimes, I will run to the store and come out & it won't restart? it does this all the time.

load test the battery. Test the alternator with a multimeter, it should read between 13.3 and 14.6 volts dc. Test the alternator at idle and rev the engine to 2000 rpm. The multimeter probes are place on the battery terminals. Look for corrosion between the battery and the battery clamps. Baking soda cleans the corrosion.
The new alternator is probably ok. I would say you burned a fuseable link in the wiring harness. The alternator has a fuse wire between it and the battery to protect it from overload. Have someone check the wires coming out of the back of the alternator. The big wire should have battery voltage, the small wires energize the alternator when you start the engine.
Yes, I agree. Overhaul, or new engine time. Loud knocking indicates your crankshaft bearings are toast-it won't be long before a piston rod goes through the block, or the engine siezes up. Overhauling an engine with a bad knocking means a complete teardown and rebuild-very time-consuming, labor intensive, and very, very expensive. You might want to consider a used replacement engine with low miles as a cheaper alternative. Good luck.
Buy yourself a volt meter and check the batter voltage before and after it starts. You should read 12 volts before starting and around 14 volts once it starts and the alternator is charging the battery. Also check for loose connections between the alternator and battery. Check that the ground wire from the battery is secured to the vehicles frame. Good luck!
New spark plugs, oil and oil filter, transmission flush and fill, fuel filter, air filter, coolant flush and fill, clean throttle body plate and bore, clean the MAF sensor, replace any loose or cracked vacuum lines, PCV valve, new air filter, new battery.
99% of the time all you should ever need for a tune up is new spark plugs, and a clean air filter and throttle body. But since your inquiry indicated "major" I gave it more critical thought.
the car won`t start in cold weather even when plugged in alternator was changed 4 months ago just changed battery thinking it was the battery but seems like something is draining the battery overnight? Maybe its a bad connection??Plz help!!!
could be bad battery terminal connections, bad battery ground, or bad new alternator - it happens all the time. get the shop that did the work to test the alternator and make sure it's charging properly.
Well, longer oil change intervals all insist on enough oil. you cannot just keep going without checking it ROUTINELY.
I am not sure about the "thought I needed more oil" either it measured low or it did not....However, situations like you describe would not usually cause engine damage, and oil would not cause no start. I suspect that something else has happened, and I suggest that you get your vehicle towed to your mechanic, tell him all of the details and have it diagnosed.
Change your oil evey 2,500 to 3000 miles, it is cheap insurance.
I drove the truck to my parent, then i try to start the truck and it won"t start/ Then said its the battery, but then i said let check the alternator. So I put my dads new battery from his jeep to my truck, then the truck started , I pulled out the battery cable then the truck stop. If the alternator was good the truck would still be on right!! Then I take the alternator to pepboy and say it pass the test , that it was good by the test machine, and to check the battery and the fuse that is for the alternator, I try to check it the fuse with a meter and seen okay but couldn't fin the one for the alternator on the truck. I hardly the drive the truck has 32000 mile the truck is a 2005 dodge ram 1500. I think is the alternator cause its making a wierd noise when accellerating. Just burn out and can't think straight.
