well, we got this crx for a nice price, but we're having problems with the batt. staying charged. i'm not really sure what the problem is... pulled out the old batt. and replaced it w/ a new one (put the old one in a friends car, he hasno problems with it), then we thought alt. nope, we swapped it w/ his and we still have the same problem... took it to a shop and they said bad grounds... re-did the grounds, but STILL Does it....
what happens is it'll start all day long, BUT when you leave it sit for a day or so it wont start up, drained batt.!

~what is there that could be draining the batt. when its off?

nothing is lit up power wise... everyone said the radio, but it had the same problem without a radio in it!

please help!

 

O.K. so here is what you do, you take a multimeter and open up the fuse box, using the leads of the multimeter you probe the fuse terminals (with the fuse out of course) one fuse at a time. Placeing one lead on each terminal (of course each fuse has two prongs, then when you find the one that is drawing power you can narrow down your search. Hope my explanation isnt to confusing, good luck with it, electrical problem can be a bitch, ive seen some people give up and just disconect the battery when the car is sitting. Oh and woot woot for my first post ever!

 

It sounds like your alternator is dead. Happens more often than you think... I changed mine like about a week ago, took about 1 hour. Its a pita to get out with the engine in though...good luck!

Almost a good explanation, but he left one thing out. Make sure you are checking for amps not voltage, he didn't mention that before. It does sound like you have a parasitic drain problem though. Somthing is slowly using up power while your car is off.

 

I have pretty much the same problem with my current daily driver. The passenger side door locks are stuck on unlock and it slowly drains my battery, to prevent this, I just unhook the neg battery cable, and then rehook it up everything I want to go somewhere. You can try that as well, to see if you are able to start it after a day or so. As J.Llyod said, sounds like you have a slight drain in the electrical somewhere.

 

yep, small drain somewhere, called parasitic drain.

the multimeter will tell you which circuit some wire is shorting out in (or a component could be left on)

then investigate what's on that circuit.

just like with dephtone's problem.

dephtone: if i were you, i'd just unplug the door lock switch or whatever, you don't need them, and it'd be easier that undoing the battery. but, of course, i'm lazy.

check every fuse? or just the main fuses? it's actually my friends car, i just do a lot of work on it... i dont think she'll be up for dis conecting the batt. all the time...

 

check every fuse.. the underhood ones and under dash..

 

Disconnect every fuse, i would start with the accessory fuses. Just keep going until you find the one that is using power. Make sure you have everything turned off when you do this too. Keep the doors shut etc. dome lights and such will mess up your test results. With everything off you shouldn't get a reading of more than a couple milliamps from each circuit that you test. If you pull a fuse and there is more than lets say 50ma being used on that circuit it means that something in that circuit is using power. Check to see what that fuse is for and it will really help you narrow down the search for the problem.

 

i had the same problem a few months ago..it was a failing alternator...

 

it isnt the alternator he has swapped that out before... dont just disconnect the battery it would be worth it to fix... find the problem using a multi-meter...Good Luck

like charliev said, we already did the alt. we swapped in one for another car that had no problems. the other car is still doing fine!
