Found the source of Battery drain...now need help to fix it.

Ok so my battery was dying on me everynight....what i did was use a multimeter and connected it in series between between my battery negative post and the negative cable. the reading i got was .70 when i took out the following fuse the meter reading went down to .01 . Anyone know what this fuse is responsible for (my fuse panel layout is in japanese) and how do i troubleshoot this circuit to fix my problem?......and another thing what is this for, and does anyone have a wire connected to this that runs to battery negative.

p.s....sorry for the crappy quality images, it get bigger if clicked on.

Well since you don't say what year/engine/trim, I guess a general answer will do. I checked both my Acura 2.5 TL and 94 Honda Accord manual and both suggest the missing fuse (4th fuse on inside 5-fuse column) is for the power seat. You should make clear exactly which fuse you removed.

I would suggest accessing manual information from autozone.com to confirm.

Unplug power seat lead and if that fixes problem, you've confirmed bad circuit. Is your power seat not working?

good luck

fuse circled in red was removed

1998 2.5l honda saber ...i'm guessing its the lowest trim as i dont have power seats, sunroof etc. and i can't tell u what fuse i removed except by showing you a photo because my fuse map is in JAPANESE. but what i can tell from the map is that all fuses are where they are suppose to be and the @ right amperage...if a fuse is missing, it suppose to be.

Can you take a shot of the fuse map next to the fuse box?

The 20A is the Cooling Fan, and the 10A says Backup, Radio. That should be your reverse lights and the radio. I've shorted a reverse lamp before and my radio, gauge cluster lights and something else stopped working.

I'll go to my other comp later and do a full translation with labels for everything else since this one doesn't have Photoshop. Do you have a scanner that you can use to scan the cover? It'd be a lot easier and there wouldn't be glare from the flash bulb.

Which fuse position eliminated the problem (row/position). We can relate this to US layout which is likely the same.

good luck

^ That's normal, since having the lights on means that you're driving at night, and a bright screen at night is a PITA because of the glare. I disabled the dimming on my screen, though.

The parking lights shouldn't be coming on with the key in the ignition. It actually sounds like you've fixed some problems.

~Cheers~

^ Even so, the lights should stay off. Even factory DRLs come on once the sidebrake is dropped, not only on ACC.

The starter and fuel pump fuses are there. I remember having to short some pins there for a car to start when the main relay went out. Didn't have gloves and got a bit of a shock, haha.

Mine is different, but it was opposite the starter signal fuse (the one that shocked me).

[STARTER SIGNAL][SOMETHING ELSE][FUEL PUMP]

Have you tried putting the fuse back, but disconnecting the whole harness for your passenger reverse light (left one), and measuring again? I'm thinking it might be the little box that is attached to the light.

~Cheers~

Try disconnecting the dimmer. I've heard of this component causing problems w/ excessive current draw.

good luck

Dimmer controls interior instrument lights brightness. It's on dash panel to left of steering wheel. Disconnect electrical connector.

good luck

You guys have installed grounding kits?

For Nissan, they have always complained about lack of grounding (ok, it is a Nissan what do you expect).

Just wondering if our cars will benefit from additional grounding.

I have two kits installed, and while it looked horrible, my original setup was measured with a multimeter to find the best grounding points. After Ken and Wilson cleaned up the wiring, the benefits of the kit diminished significantly, although it's still better than stock. 96's have problems with audio whine from the coil packs, but that was addressed for the 97 and 98 models.

It's GOT to be your reverse light. Check for a break in the line. It could be shorting out against chassis.

Yes, they go out. Purpose of disconnecting was to determine if the dimmer was source of drain. Have you checked for drain w/ dimmer disabled? If disconnecting fixes drain, then dimmer needs to be replaced.

good luck

What I meant was between the fuse box and the harness, there might be a break in the line that's grounding to chassis. Hate to say it but you might have to take apart the panelling and follow the wires to find it.

^ And find out what's causing the fuses to blow, as I can guarantee is related.

i 4got to inform you guys that there was actually a 20A fuse in place of the 10A, which from the fuse map is clearly the wrong amperage. this fuse was in up until my problem started.
