Question about 1993 Eagle Talon
Kenneth, have you checked amperage draw on this vehicle? To me, it sounds like you have a component that is staying powered up even with the key off, which could be a component issue or a wiring issue.
You should check for an amperage draw with the key off by doing the following:
Be sure that key is off. You will disconnect the negative battery terminal and connect a Digital Volt/Ohm Meter (DVOM) with the black lead on the battery terminal and the red lead on the cable end ( the cable should not be touching the battery at this point).
Set your DVOM to the amp setting (A) and check what the meter reads. You should wait at least 2-3 minutes before you get an accurate reading as some components, such as the engine computer, may take a few minutes to power down fully. You should see a 0A reading at this point- if not, you have a big draw and should not continue to prevent damage to your DVOM.
If you are reading 0 in the A scale, switch to the miliamp (mA) scale. You should see less than 500 mA (0.5A) reading- this is a general rule of thumb as some things, such as clock memory, radio memory, ECU memory, etc will create some draw, but even 0.5A draw will take several days to draw a battery dead.
This will at least tell you if you have a parasitic draw on the battery causing it to go dead.
Hope this is helpful!!
