Battery Randomly Drains
 

ok i've been having this frustrating situation for a while now... i connect the battery cables to the terminals and with in a few days my battery is completely dead (no lights on the dash turn on as if the battery isn't there at all)............ any ideas anyone

BTW here is a short clip showing how the cables are currently connected

I am having the same issue. No lights are on at all. The only thing I can think is maybe the aftermarket stereo is draining mine. But, I don't even have the face plate on the stereo. So, I too am looking for others who may know.

Passive restraint system fuse
 

I had a random power drain on my Z and it turned out to be the Passive restraint system (seat belt). It releases the tension on the seatbelt or something when the door is open. I pulled the fuse for it from the fusebox under drivers kickpanel and the power drain went away. I never had the issue fixed and the Z died from other causes before I could look into it more.

What year is your car? (The specifications of your car [NA/TT and year] should be included in almost every thread in which you're asking for technical help.)

Do you have an aftermarket alarm with active sensors (impact, motion, etc)?

Do you have an amplifier that is wired directly to the battery without a control wire going to a switched power source (like the stereo's control wire, or some other ignition-activated power source)?

How old is your battery?

sorry i took so long to respond been working crazy hours... it's a 1990 N/A factory EVERYTHING no sound system, and that battery was just bought 2 days before

pull the ground strap. hook an ammeter between the battery post and terminal. see if you see a drain. if so start pulling fuses to see if it goes away. if no drain then charging system suspect. take it to a battery shop for analysis usually free.

I had a problem with my " alarm " yellow light always staying on draining my car battery on mh 1993 300zx n/a auto. 2+2 it still acts up sometimes.

i recently took out my factory alarm cause my dad said he saw my headlights on one morning so i think that could be the problem for now
