Did some searching, couldn't find anything helpful... Bare with me as I try to describe what's happening and thank you for helping!!
To start off, I have a 90 civic hatch. 2 days ago, my car wouldn't start. Put in key, lights come on, turn key, starter tries to click once and slowly dies out.(2-3 seconds) I charged my battery that night and the next morning it turned on fine. Last night it wouldn't turn on (8 hours after i drove it) and did the same as described before. Charged again last night. Turned on fine today and drove for an hour. Got home, turned car off for a few minutes and tried to turn on. Same issue I've described. Now, I have a new starter, new alternator, new battery and new pos cable. Do I need to replace my neg cable or battery? If not then what's draining my battery so fast?

 

This is basic troubleshooting info. Place a test light in between the neg cable and the battery post (using the test light as a continuation of the neg cable) then pull fuses one at a time and put them back until the light goes out, this will identify the offending draw. Then you need to LOOK for a solution to the problem instead of not thinking with logic to find a viable repair. Good luck. I have found that most of the time the issue is aftermarket equipment not properly installed in the first place.

I don't understand your not thinking comment but I'll do the test light. And all my aftermarket equipment which meets OEM standards, is all professionally inspected after being installed. The new parts have been on my car over a month now and this battery issue just came up 2 days ago so its not anything I've installed causing it to drain.
Edit: I'm gonna charge the battery and test the fuses with a multimeter, how you were saying. I'll update tomorrow after it charges tonight.

 

Where did the battery come from? It may be bad out of the box, yes it happens, you want a battery built by johnson controls I have found after many years these work best and last longest. I was not trying to insult you, merely get you to think about processes in your car that would cause these issues. You need a helms manual, it will be invaluable in your troubleshooting. ALL others are inferior and are not going to give the results you seek. Any aftermarket equipment can fail. I have, in the past, performed custom installs in exotic automobiles, boats and RV's. I have seen a lot of equipment fail out of the box or had a very short service life. START HERE, disconnect all non oem equipment and see what results you get. I also am not saying that you have purchased junk, just offering a possible solution. I have installed a lot of expensive, high end equipment that failed instantly or not long into service. If you have replaced any component with a "big box" remanufactured or rebuilt item, PLEASE remove it, and replace with a NEW not remanufactured or rebuilt item. I have used these items in the past and got tired of replacing the items over and over, I have better things to do with my time. So will you at some point. Good luck with your quest.

Its a box battery from bimart, and thank you Dave. You've given me some valuable information. I haven't had time to look at my car this weekend but I'm getting it dealt with today. I'll post with update of whether I fixed it or not. Thank you!!!
