66 mustang won't start :(

I left the starter position in ACC and the next day it was dead.
Bought a new battery and worked great for a day but dead again next morning. Now I cant even jump start it. What can I do?!?

Not trying to be rude, but it can be anything. If you have a wiring diagram and can do the diagnostics, start at the battery and check power and ground. Does your solenoid do what it is supposed to? Is the voltage right at the coil? If you can't check these yourself, you should get it to a good mechanic. Almost noone can diagnose properly without putting their hands on the car.

I'm wondering if your battery cables are clean and tight.

I bought a battery charger and it's working but if that happens again, I might take it to a mechanic to see if its the alternator or other of the things you guys said. The cables are good and new battery. So hopefully wont happen again,
Thanks for your advices.

You can put a volt meter on the battery terminals to check the alternator. Parts houses will check it but I (think) you have to take it off.

No, you check the alternator by starting the car, then you remove a battery cable from the battery. If the car dies, it's your alternator. Putting a meter on the battery terminals will only give you battery voltage. Also, good voltage doesn't necessarily mean it's a good battery. You also have to check amperage, hi volts but low amps isn't too common but, it can happen.

Yeah, it is the alternator I am pretty sure. The car dies after the battery lose charge.
How expensive is an alternator for this car? Is it easy to change?
I guess its the price for having old cars but I love my mustang so it worth it.

Any suggestions of brands when buying the alternator?

Depends on the size motors you have as far as cost. It could be anywhere from $60-200. As far as changing it, it is either 2 or 3 bolts again depending on the engine/bellhousing and the battery wire.

Just make sure you disconnect the lead from the battery before doing any work with the starter.

All 66's used the same type alternater. If its a driver brand is not very important. You should have several options at any parts store. They can advise. Get the best warranty you can.
