Well.. on with the show. Today I tackled two things that were bothering me. 1. A dent in the rear chrome trim piece around the back window.
2. .. Parasitic draw...

1. Let's break shit! I always feared doing this. Ugh.. and ya. These clips are crazy. Go slow...


I don't know what these are or how they get here.


The dent...


= Old


Adding extra support.


Fini



#2.... Parasitic Draw. Well..... I know I have a draw. And I've been ignoring it. Got a new multi-meter as I blew my last one using the wrong settings trying to solve this... anywho.

I have .80ma and sometimes almost 1amp draw on the battery with everything off.

Good news:
- It's not the horn (one horn is disconnected.) It has 0ma draw
- It's not the ECU
- It's not the door lights

Bad news:
- With all the fuses pulled from passenger side I still have .1ma draw. Is that ok? I think it is.
- It is the "radio + internal lights + bunch of other crap is drawing crap.
- The condenser fan is pulling 1ma alone..., relay??

Going to dig into this more tomorrow.....

I see you have a stereo system... do you still have the automatic antenna? I don't remember ever having a problem with parasitic draw it until I installed an aftermarket head-unit in mine. Maybe try unplugging/disconnecting it and seeing if your power consumption lowers? It's at least a theory I meant to check on mine, but never got to before I parked it.

Ya, will check it out. Power attenna is gone but the wire leading to the attenna is there and plugged into the stereo. I'll see if it makes a difference.

So with every fuse unplugged and even the large connectors on the drivers side I still have a 1ma pull. Ya....... I'm not chasing one milliamp. But on to the big ones....

12ma - Stereo
10ma - interior light (all lights were off, trunk bulb pulled, doors closed)
4.6ma - door lock (not sure on this one yet....)
2.0ma - condenser fan (ahh don't think I even use this, but not 100% sure what fan connector I'm using. Probably the rad fan and not the AC fan)

Oh. Antenna was not plugged in.

Alright...

12ma - Stereo - No idea. Still pulls 12ma with stereo removed. Did drop to 6ma when i removed the stereo harness. (Stereo does have a brain unit which sits under drivers seat to control amps, ipod interface and ....hmmm entenna. Ahh thought that was it. Pulled all plugs on brain unit but same results).

10ma - interior light (all lights were off, trunk bulb pulled, doors closed). No idea on this one yet... even pulled most the bulbs.

4.6ma - door lock (not sure on this one yet....). Ug.. really not sure on this. Did not try unplugging lock relay box yet in the drivers door. All the locks work fine

2.0ma - condenser fan - ya... not in use. Will test next startup. Left fuse out.


I think I'm ok with the stereo drawing 12ma for whatever reason it does.. (IE: monitor parking brake for off mode.) But sure would be nice to know what exactly is drawing the power. Tomorrow I'll try removing the cig lighter too.

No way door locks should draw anything.

Interior lights should be an easy fix as soon as I remove all the lights.. Hopefully...

All your mah numbers look good, and aren't anything too crazy. Need to figure out what the large (1amp) drain you said you sporadically see is.

What's the CCA of your battery? Divide that by 7.25 and you should have your relative amp hour (Ah) capacity. (E.g. a 650CCA battery can store about 89.6 Ah). With a 10 mah draw it would take 373 days to drain said battery. At 50mah would take 74 days.

I presume you have an Alarm, have you checked that as a source of power draw? Or pulled the fuse out of your main battery feed to your amps and see if that helps?

750CCA / 7.25 = 103Ah
total ma pull is 28.6ma

.....

2.6??

There are 1000 mah in an Ah. So 103,000mah / 28.6mah (consumption over an hour) / 24 (hours in a day) = 150.058 days. So if there are no other drains, your battery (under ideal conditions), should last that long before being drained down to nothing.

No. it dies in 5-6 days with a 30amp drain on it.

For it to drain that quick (provided you have a healthy battery), means you are drawing on average 859mah/hr. So something is sucking a descent amount of power.

How much power is your stereo, and/or alarm drawing? What about the fuel pump / PGMFI relay? (They've been known to have solder issues, maybe the relay is stuck on, and your fuel pump never turns off? - Try some "percussive maintenance"?)

So the battle continues. We had.......

12ma - Stereo - Finally got down to 0ma, but not sure what did it. I basically unplugged everything in the car. As I plugged stuff back in, it never came back. Today I need to continue plugging things back in and see what happens.

10ma - interior light. Still no idea. Now pulling 2.6ma now with the car totally apart and not sure what this would be.

4.6ma - door lock - NO IDEA. This one makes no sense to me. All doors and locks work fine. Even with all door lock switches unplugged it still has an issue.

2.0ma - condenser - Not in use.

Ok, got stereo down to 0ma, by unplugging everything.

The 3.8ma for the door locks is coming from the door lock control unit box. Makes sense as it needs power to perform an unlock/lock feature with the car off.

Still cannot locate the 2.8ma off the interior light fuse. Think I may let that slide too.

Assuming I can keep everything quiet once plugged in we are looking at a 7.6ma drain on the battery. This website states this is 98 hours to drain the battery. But i wonder how many hours or days it would take to drop the battery 2V from it's 12.8V charged state.

Yaaaa, add 2.6ma for power folding mirrors. makes sense though..

So 9.6 or 10ma drain so far. Looking good.

So in the end the total is around 13ma. Having the stereo plugged in took the 9.6ma total up to 13ma. Fini for now. Starting to think i have a bad battery too.

Put the car back together and started up no problem. Everything works fine. Put a charger on the battery and it's at 12.57 or something. Going to see how much it reads tomorrow. Fuses left out (put in by shops?) was the sunroof fuse, condensor fan (confirmed today that the fan still turns on),

Oh, finally found a seat handle. I was always missing the drivers seat handle...


And did this mod...

Took Sally for a drive today. Only issue is the stereo few out while shifting
She still spins tires in 3rd and 4th no problem. 3rd is the fun gear though. And she always seems to attract others and gets lots of waves!

But she needs another resonator. Still too loud....
