How long did the 2nd alt. last before it died? The voltage regulator is, I believe, attached to the alternator. Have u had the voltage regulator checked?

The instructions for installing a new alternator usually read to fully charge the battery (12.3 - 12.8 volt range). Otherwise, the alternator will be damaged when it initializes. I have seen some extreme damage result from installing a new alternator with a low-charge battery. The torque required to turn an alternator when damaged in this scenario is unbelieveable!

Check the main power fuse that goes to the alternator output. if the alternator went out it could have burnt this fuse also.

SOURCE: installed new alternator and car battery still will not charge.

did you unhook the battery prior to installing the alternator

HI. you may have a battery drain issue that is sapping your battery overnight.

Here is the procedure I use to isolate a battery drain. Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or "light" if there is a drain. If the "light or glow" is faint, that is probably normal draw for the clock or computer. If the "light or glow" is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain. Remember to hold in the button in the door jam for the interior lights.
