1993 Mazda 626 Won't hold charge

I have a 1993 Mazda 626.

I have put in a new battery and alternator.

The battery was fully charged before installation. It held for 2 days.

I've checked all the wiring from the alternator to the battery, I changed the ground cable. Recharged battery at Auto Zone, still will only last two days.

Why is my charging system not working?

Occasionally rebuilt alternators are defective right off the shelf. Start your engine, then get a battery voltage reading. It should be at least 13 volts with engine running. If not, then your alternator is bad.

It could also be the fan belt. How long has it been since it's been replaced?

Your charging system may be working, you may have a drain on the battery
Try Lugnut's test
Test the voltage after the car is shut off
Test the voltage the next morning before you turn the key
