I had a drain on my battery that was intermittent. It would drive me crazy. I finally found it. It was the door / headlight / parking brake chime. I just unplugged it. Everything is fine now. It did NOT make noise when it was killing the battery. It's a easy thing to try if you are having problems. Anyone else every have this issue?
I had the exact same issue on my 86 until I pulled the complete interior out including the chime and a few other boxes under the dash... I just left the chime out bc it bothered me and out of pure luck it quit draining
I had a battery drain on my 84 Indy as well. There was a .9 A !!! drain that would kill the battery after just a few days of sitting. After searchuing the forum, I came upon this post about the wonky chime unit . Funny thing is, I never heard the chime with the ignition key off and headlights on, door open etc. Once I pulled the chime unit out from under the pass side dash, no more battery drain!
I had a major power drain. Turned out to be worn headlight motors (no noise). I disconnected the single power wire to the right and left headlight and like Magic, I was able to charge the battery. Befor, the power drain was so bad, I couldnt even charge the battery.
I did not hear any noise coming from the door chime when parked either. Also it would not always drain the battery, some times I would park it for a week without the drain on the battery and sometimes it would drain in just 24 hours. It may have something to do with humidity but I haven't proved that. I just pulled every fuse unit the test light went off. The test light was put between to the disconnected ground cable and the negative battery post. I pulled the interior light fuse first because I was doing this with the door open that would cause a drain with the interior light. The chime is on the tail light fuse. I hope this helps anyone who has this problem. By the way my Fiero is a 1984 as well.

My 88 had a phantom chime, while driving it woudl just randomly chime once. It could have been a slight drain when parked. I disconnected it. I dont really need one, for me they are more annoying than not having one even when they work right.
Battery drains can be a real pain to find. I had one I tried to find for months. Turned out to be a bad power window switch. Somewhere in its life, they had been wired battery hot instead of ignition. I thought it was great that I could use the windows without the keys. Once I replaced the one switch and wired it to ign hot, it stopped.
A battery drain problem I found once was my amplifier. It was an old PPI amp. The blue turn on wire was getting switched power from the head unit but somehow the amp was staying on even when the head unit was turned off. That sucker drained the battery in about a day and a half. Had to put a solenoid on the main power to the amp.
On the dingy thingy topic at hand, sounds like I will be pulling mine soon now too, It has been randomly chiming here recently for no known reason.
