Why would a person assume I'm too stupid to check that out first before posing a question on here? And what person wouldn't realize an 87 Cadi doesn't have parts at the dealer anymore, and most have been destroyed at junk yards, so parts are nearly impossible to find at pick and pull. Come on, people, I need real answers. Who can help me?

It sounds like you have an electrical draw on your battery. First disconnect the possitive battery cable at your battery. Take a test light and clamp on to the possitive battery cable end. Probe the possistive battery itself. If the test light lights up than you have an electrical draw. I would recommend pulling each fuse one at a time until the test light is no longer on. When the test light is off than you will know which circuit the draw is in. Be sure to check for basic stuff like the glove box, trunk light, power seat sticking, delay lights, etc.

Yes, go with Mr. BIG! It may charge just fine, but if the regulator isn't working correctly, it can leak current after the engine stops and drain the battery. Try putting a different one in and see if that makes a difference. I'm going to assume that most any GM alternator from that era will work in that car, since they were mostly the same.

If your batter is being drained fast, Like within a few hours etc... It is probably your starter solenoid. If it a slow draw do the fuse thing advised earlier. If you battery has been drawn completely dead too many times it might be junk too and might need replaced after you get the short fixed. Hope I have been helpful

Clean your battery terminals. Even though the alternator is good, if the voltage can't make it "into" the battery, your battery will lose voltage. If you've already done that, then start cleaning other connections, like where your battery grounds to the body.

Is your battery good? How about your grounds to the chassis and starter? I think your car is old enough that a coil or distributor could be arcing to ground and causing it to discharge. Also, some cars when the radio is left on will discharge the battery, my '04 GTO does that, talk about stupid....hope this gives you some direction

If all of the previous advice fails, it is possible that the 'short' is inside the battery. Try a new battery and see if the same thing happens.

Also, your alternator can still be bad if the internal voltage regulator leaks then it can kill your battery when the car is off.(even though it is charging) disconnect your battery over night to check. If all else fails.Good Luck.

Sounds like 1.) bad wiring or 2.) bad ground (most likely cause)..... just clean the wire connections, and clean where the ground connects to the battery and to the frame or wherever it is grounded to
