Alternator?
So my Supra is in storage and has been getting started once a week. I just installed a optima yellow top before it went to storage. My family called to let me know that the battery was dead. It has been cold there so I didnt think a whole lot about it. So I went home and fully charged the battery, now it is dead again after a week or so. Thoughts? Alternator?
Thanks in advance. BP

Sounds like you have a current draw somewhere. A volt meter will help find it. You could place the leads onto each battery post, then pull fuses one at a time to see which circuit is drawing current.
The voltage meter will read a bit higher when the correct fuse is pulled. Then go from there. Also, whenever storing the car for more than a few days, remove one of the battery terminals from the post.

Thanks for the help. So if I can get it fully charged again, just disconnect the terminals and I should be ok till it starts getting driven every day again? Maybe I'll see if optima will replace it for me, it should still be under warranty. Any other ideas? I will for sure be installing a capacitator for the stereo this year as well. I bought the yellow top because I thought it would be better for this sort of thing.

Well it has been sitting discharged for 2+ months now then. I talked to optima and they will replace the battery under warranty so when i get the new one ill just leave it till I can start driving it again. Yes?
Any easier ways to find what is drawing power when the car is off?

There's an 'old wives' tale about not letting it sit directly on a concrete floor, but that myth has been 'debunked' afaik. Quote:
Generally though, an unmodified/factory/oem vehicle doesn't draw very much current at all when the vehicle is sitting. Many abnormally high current draw situations associated with prematurely dead batterys are related to mods/upgrades. I'd suggest you start the fuse-pulling exercise with any circuits associated with any aftermarket electronics modifications on your Supra, such as boost controller, fuel controller, gauges, turbo timer, security system, stereo system, etc...

So Im getting a new battery free of charge from Optima, sounds like it had a short in it. Could this have been the real problem, or do I still need to find the draw?
