diagnosing battery drain
 

I have a severe battery drain on my 1993 Honda Accord. I put a new battery in it this morning and everything was behaving beautifully. It sat until about 4:00 this afternoon and it was completely dead.

I put a meter on it to see what the draw is and if I'm reading it correctly, it's 2.61 ma. I've gone through and pulled most of the fuses one-by-one and no change. I then pulled the main 80 amp fuse and still no change.

If I'm understanding this correctly, that means the only thing still connected is the starter. Is that correct? What does this mean? The starter is bad, or maybe there's some relay somewhere that is bad. Where do I go from here?

Thanks for your help.

you could go to posting in the correct forum and showing some respect to this website.

It says over and over at the top of this forum not to post questions here.

Your question belongs in General Tech

Which is where I have moved it to..Please post in correct forums...

Sorry. I tried to respect the site and find the right forum, but since you have 25,000 posts between the both of you, it might be a little more clear to you than a first timer. Thanks for welcoming me to the Hondaaccordforums.

Welcome to the forum!

Is your battery charge light (battery light) on the dash on when you shut off the car? If it is, it may be a faulty diode in the alternator allowing current to go in the wrong direction and drain the battery.

Unplug the alternator and see if your current draw drops to a normal reading.

agreed, disconnect the alternator and see what happens, if it's internally shorted it will cause a drain...seen it many times.

and for the record, how exactly did he show disrespect? the only disrespect i saw was your snide remark.

TitanTn,

There are plenty of members here willing to help. :)

If draw is 2.61 ma as stated you have no draw to speak of. Pls check your test may it have been 2.61A not ma A new car has up to 30ma draw and be ok

Thanks guys. I'm not really sure what I was measuring. I was getting consistent results from the meter the other day and thought I had identified the volume of the drain. Today, I cannot get the same results. I cannot get either of my meters to work right. Neither of them will even read the voltage on the battery without it being connected to anything. I'm wondering if I've screwed them up somehow. I guess I'm going to have to buy another meter and see if I can get an accurate measurement on the voltage drain.
