A car will run fine on a charged battery using juice from battery to power ignition system which will drain it.

 

you forgot to mention "for about 15 minutes"

the car nearly drains the battery to between 2-9 volts depending on the starter demand.

 

nope its a 3 month alternator and a 7 month battery found out whats it was just hoping got it fixed the courtesy lamp fuse was blown so i left it out and charged the battery just gotta wait till morning

 

So the fuse was open? If so this would not cause a drain and therefore removing it will not make a difference. Just a thought, look in your glove box to see if it has a light. If so make sure it is turning off when you close it.

 

OK
Froggie, dont get hung up on how new it may be, things go bad no matter how new. Do you still have the factory voltage regluator for the alternator?

 

^ i was about to say something about that. my 86 has an alt. from a 71 mustang 2 and is EXTURNALY regulated. there for the alt can be good but if a wire pops off of the regulator or if it goes bad the charge wont get the the batterie.

and when i first got my red top optima it took a crap only after having it for 3 weeks. but i got it replaced free of charge.

 

sorry havent replyed to thred got it fixed it was a blown fuse for my courtesy lights and now its running like a champ again....and no regulator engine is not original also this car is in good shape like the engine and body but everything else has been abused my dash hardly lights us need to get a right way for my radio to be wired right umm need new top deck and main plastic for dash need the buckets done with new fab and get the tracks cleaned so i can finally sit in it right.........

 

What was the issue with the battery?

 

can someone explain how an open in a circuit will cause a drain on the battery?

 

I think the open circuit was to fix the dash light issuue
