Okay, if there’s a thread for this please feel free to redirect me.

• My alternator and the belt for it does not start once I jumpstart my car.
• The battery works great and car instantly starts upon being jump started.
• belt had been squealing for some time now, upon first starting vehicle (I assume this is from the alternator needing to charge the battery from the last drive)
• belt does not spin at all when vehicle is running. (This is why I assume the alternator is not charging the battery and the vehicle dies within moments of removing the jumper cables)
• I had someone suggest this may be the pulley system.. my sisters had broken on her ford not long ago

with this information, any assistance is appreciated. Thanks!!

 

Well, that belt goes around the crankshaft pulley, the alternator, and the AC compressor.
If the engine is running the crankshaft pulley is rotating. That leave the driven components, the AC compressor and the alternator.
Turn off the A/C, that disengages the AC compressor clutch so that pulley will freewheel. That leaves the alternator.
If with the A/C off the belt still isn't moving maybe the alternator is seized

But if that belt isn't moving at all with the engine running I'm surprised it hasn't snapped yet

 

You can remove the belt and see if the alternator is stuck.

RX first gen can operate without the belt for at least 10 miles [depends upon battery strength].

so just to confirm… if the engine is able to turn over then it’s not an issue with the pulley system.. and it’s most likely that my alternator has seized up and needs to be replaced?

 

Not sure what you mean by "pulley system". The belt is driven by the crankshaft and drives the a/c compressor and alternator. It is not a serpentine belt that wraps around everything and may have tensioner and idler pulleys.

There is no way that crankshaft pulley is stuck with the engine running so if the belt isn't moving it's one of the other two.
But really if the belt isn't moving with the engine running I'm surprised it hasn't snapped. How is the belt tension? Did you try turning off the A/C?
