somethings draining my battery
ive got an 86 rx7 base. something is drawing my battery down and its an optima yellow top. my car has an aftermarket viper alarm and i thought that maybe the factory alarm might have been drawing power. but after doing a little bit of research the alarms only came factory starting in 88, so thats not it. all of my lights work and none of them are on. if there are any other questions you have that would help you help me id appreciate it, thanks

Just to add, if you don't do the test we asked you in the other thread, we can't help you.
Do the current draw test outlined in the other thread you posted and post the results.

Was there any change to anything prior to this issue arising?
Install a new amplifier? Re-wire alarm? Replace alternator? Anything?
Undo the last electrical thing you did and see if the problem remains.

normal draw with a viper alarm is going to be about 30ma maybe 40ma.
If you have something like close to 200ma, I'd say a relay is stuck on. If the test indicates normal draw, then I'd be suspicious of the battery (it might be damaged already by the drain).

that's because they aren't stock, so nobody on earth knows what they are because they aren't supposed to be there in the first place

ive put 3 different optimas in it(my yellow top, and my s13's redtop and my roommates soarers redtop) and theyre all doing the same thing, but you put it in another car...granted you have to jump it cause the rx7 kills it. they charge and stay good. so i dont think the batteries are going bad. but ill definetly check the multimeter when i get hom and let you guys know. and just to verify on how to do this:
disconnect positive terminal battery
touch leads from multimeter from post to terminal
read numbers
post them here

Remember to be measuring in milliamps (mA) and be sure the leads are plugged in correctly to the meter do measure current draw.

Did you check the draw w/the other batteries hooked up as well especially the one which works the best? If the curent battery still indicates a large draw then pull the BTN fuse and recheck the draw and if it doesn't change much for the better then disconnect the alternator output wire and check the amperage draw once again.
