the pics of ur car wont help us solve the problem...lol..j/p...nice ride

sounds like u have some type of drain..a circuit may be staying on while the car is off..make sure anything that is hooked up that is not factory is wired correctly to shut off with the ignition key off..if its not then it will drain the battery..could also be a factory circuit though..but i woud start with anything aftermarket..could be why the car was sold to u...

I had a similar problem about 9 months after installing my TYC HID's...
They worked perfect before that, then all of a sudden the driver's side light started strobing. I had to take the fuse out for that side because every cop that I passed on the road pulled me over.

After taking the car to several "specialists" who could not find the problem, I decided to take a multimeter and try to track down the problem myself. Found it in about 20 seconds. The leads feeding the HID's had somehow broken free of their cable ties and were sitting on one of the pulleys... which was gradually sawing through the leads. I wasn't haven't any battery problems though, which is a surprise given all the electrical problems I've had with this car.

Obviously something is drawing power while your car is off, so if I were in your position, I would:

Get a multi-meter that has the clamp end and the ability to read DC amperage.
Clamp it around the wire connecting your battery to the chassis.
With the car off, it should show you that there is some DC amperage present.
Start pulling fuses until you find the trouble-causing circuit.

Its a crude method, but its guarranteed to find the problem.

Hope that's more helpful

Is 7.5A fuse 15 under the dash blown?

 

.......

 

It would be best to just replace the fuse with a known good one. If it's blown, also check whether the new one blows again.

If you haven't already, also sand clean and tighten the battery ground wire and the large wire on the alternator.

Any CEL codes? Does the dash battery/charge light remain on while driving?

 

;;;;;;;

 

bump. i need me some

 

Do the CEL and battery light work [i.e., they turn on when key is turned to ON(II)]?

Fuse 15 protects multiple circuits, including one for the alternator.

 

daaang good luck with this problem... I had a similar problem draining battery drove around w a spare too... new alternator... turned out it was a fuse.

 

it was fuse 15 (alternator)

well everythings fine. hopefully it stays this way thanks everyone

 

Nice find. My old SVX had battery gremlins that nearly drove me nuts.

 

LOL at driving around with a spare battery....
When not driving, simply DC the cable, and the best way to fix the issue is finding the issue.... Start tracing wires/fuses

 

.......

 

If fuse 15 happens to blow again, then read this TSB.

Did you check whether the fuse blew again?

 

 

dizzy? cat?
It could be that it was cold when you revved it to 7k (if this is the case that's bad, don't rev that high when it's not at operating temp!!)

haha..but it could be electrical..I know the civic fuse box is in an annoying place, but check ALLLL of them and replace all the ones that look suspect. Check all the relays as well. Relays are known to intermittently fail.

RON!
you are an awesome honda technician..I've been lurking for awhile and you really know your stuff sir!
(And you're only 4 hours away!)

 

+1 Ron. I've been lurking around for a bit and it's clear you know what you're doing. Thanks for the solid input.

 

vouch, ron is the man!
