What is causing the Diodes in the Alternator of a '93 Topaz to keep burning out and draining the battery of it's charge while sitting?

most of the time the diode circuit will burn out trying to keep a defective battery charged, which results in overheating or increased amperage for the charging circuit which includes the diodes.

Your battery drains on your 1988 Chrysler Fifth Ave you were told it maybe the idle control sensor you had your battery and starter checked by your battery is still draining?
Have you had the alternator tested? It may not be regulating the energy to the battery, causing it to drain
My car died while driving last night so i replaced the battery. AutoZone tested the alternator and said it was working but it was draining my battery slightly...what could be causing this?
Don't believe a word AutoZone tells you. My battery died so I went there and they tested my battery and alternator and told me it was the battery. So I bought a new battery and 2 days later, dead again. Went back and they tested again and THIS time, it was the alternator. I went nuts on them and ended up getting both my battery AND alternator for free for their mistake that left me stranded at 12am.

If you constantly run your car with a dead battery will this hurt your alternator?
Yes, alternators are designed to maintain the battery, or recharge a battery that has been slightly discharged from starting the car. When the alternator is used to recharge a dead battery, it causes the alternator work harder and longer than it is designed for, causing it to overheat, thus causing damage to the alternator. A battery charger should be used instead. They are designed for charging dead batteries. After the battery is charged, let the alternator maintain the charge.
Why is Battery discharging mustang 1971?
First have the battery checked, then perform a test where you observe a volt meter while you disconnect different systems in the vehicle, when you have stopped the drain you have found what is draining the battery. I would look first to the wiring harness where the alternator wires merge into it, i had a problem with mine and some melted insulation causing massive problems with the electronics. the alternator is always a good place to look.

Why does auto battery leak after charging?
An auto battery could be leaking for a couple of reasons. The alternator could be overcharging the battery causing the leakage. Or the battery itself could have a short or other internal problem causing it to leak when charging.
Will the altnator lock up causing car to stop?
It can happen. The bearings on the alternator of my Silverado did that once, and it ended up causing the vehicle to shut down. the alternator on your car charges the battery which in turn runs the electrical supply to the car. if your alternator is damaged the battery will deliver power to the eletrical system until it no longer can and the car will stop running.if i were you i would replace the alternator,recharge the battery if it is still good and then happy motoring.

What could be wrong if the battery is good and the alternator is good but the battery keeps being drained?
Something is causing a drain on the battery even with the vehicle off and nothing turned on. A good mechanic can do a drain test on the battery to see what may be draining the charge. A dead cell in the battery itself will also cause the battery to go dead. Disconnect the negative battery cable overnight and if the battery is dead the next morning it has a dead cell and must be replaced. If not look for a light that is on or a relay that is stuck.
