Get a test light and disconnect the negative battery cable now put the light between the cable and battery negative post is the light On? If so start removing fuses one at a time -the fuse that turns off the light is the trouble circuit. Then break out the electrical wiring diagram.
In the event you removed all the fuses and the light is still On disconnect the alternator batt. Feed and the connector-if this one turns off the light-the alternator has bad diodes.

I have a 1989 Cherokee that is having the same problems with battery drain when the key is off. I have removed the fuses one by one and my voltmeter still reads full voltage. (I used my voltmeter in place of a test light.)
Would someone be able to explain the above quoted recommendation to me please? I don't know what it is referring to by the " alternator batt. Feed and the connector".
I apologize for my ignorance and thank you for your assistance.
