Question about Cars & Trucks
The battery and alternator may have been ok.
You have a fuse or fuseable link between the alternator and battery to protect it. If you have battery voltage at the battery post and not at the alternator post, there is a break in that circuit.
If the battery cable goes to the starter, the alternator wire may go from there and that could be where the fuseable link is.
Fuseable links are special thin wires that act like fuses.

12 volt is actually a misnomer of sorts... it's actually closer to 13.8 volts i believe. if the voltage regulator is not working right you could very well be frying the battery. replacing it is the cost of the alternator + labour (unless you do it yourself).

sounds like the starter is not engaging the flywheel if the starter make noise like a power saw and the engine is not cranking may be the starter solenoid is not working I have seen this happen whit brand new starters now before you change your starter again ask some one to turn the key for you and see if the crankshaft or any otter pulley is rotating. if noting turn then replace the starter again and ask them to tested for you at the store and see if the gear comes out like it shut. If you see the crankshaft and pulleys rotating but the engine wont start you have otter problem if the engine hardly turn whit a fully charge battery or jump start from another car take all spark plugs off and tray again whit out the spark plugs if coolant comes out of the engine you have a floated cylinder and a blown head gasket. Note may be a good idea to change your battery clamps wile you are at it or at leas clean then using a wire brush bad contact on battery clamps causes to lose power doing start. hope can help you good luck. :)

turn your vehicle on, disconnect the battery, both terminals(while truck is still on) if it dies on you, then either the alternator is bad or wiring is wrong. if it stays on, then you may have a bad battery or voltage regulator. Check the voltage on the battery before you turn it on(should be from 11.5v-12v), when you turn it on if the alternator if working properly you should have around 13v-14v.
