I am on the fence what I want to do with this one.... I am not gonna lie, the rattyness is growing on me. I think it's kinda funny. There's A LOT of rust on this thing... Sure, it could be fixed, but its going to take some time. Good summer project I suppose.

Tony, on my multi-meter, I had it set at the 20mA setting when I got the reading. Update on it too, I've left it sit over the last few days and it was still draining the battery, but not as bad. I could still start it up fine. Once I get that 318 up here, I thought about using the battery cables and such to relocate the battery to the trunk as well since the current setup is very hacked.

So does that mean that if it read 4.07, does that mean 4.07mA, or 40.7mA? Either way, that doesn't sound like much.

well it's the same as .004 amps, so it's not much. I'd start testing the components on that circuit to see which one is drawing the same at the other end.

Well, if that's the case, then its probably something else. This circuit has things like the clock and the SI board thing. That stuff draws from the battery all the time I think so I don't know if this is actually a power draw.

what's the total draw on the battery with all fuses in and engine off?

Just what I said. The 4.07 on the 20mA setting. I'll double check this week.

yeah, I don't think that should be enough to run the battery flat in a day or two. Have you had the battery tested?

Brand spankin' new baby. lol

I am going to throw it in and let it sit for a few day without turning it on at all. I did have it running for awhile. Perhaps its not charging the battery well with the frayed battery ground strap.

I thought we tested the alt. voltage too and it was around 14v's though.

Also, one other thing... I am picking up a set of bolted 14" snow tires.... :) :) :) :) I's gonna ice race this bad boy! ;)

Well, obviously this is not what we want to see.... but do you think it is possible that the route of all the problems are stemming from this lovely piece of wiring awesomeness???

This is the battery ground cable... Clearly it should be replaced... but just looking for comments on whether or not you think this could be the cause

Also, Does anyone know of a write up or something for relocating the battery the trunk? I am going to see if I can just use the setup from the 318is to put the battery in the rear. I am just not sure if it is as easy as unbolting the cables from the 318 and and mounting it to the 323...

It will be a direct swap, but do a voltage drop test to be sure your new connections are good.

Here are a couple good resources:

Dunno what you're talking about... those wires look fine to me....

*snickers*

I'm not sure it's the cause. Usually spikes are caused by bad grounding in total but also a broken alternator can be giving WAY too much voltage or something if unregulated.

Thanks yoshi, I'll start here I guess. LOL! That would be nice if this is all it is. My luck, it won't solve anything. ;)

Well... you have a plug and play right? Voltage spikes from my past were all due to me grounding in places that shouldn't have ground. or accidental voltage backfeeding. All sensors are ground back to the ECu, then the ECU is grounded to the engine block. My engine block had 2 thick ass grounds back to the chassis. After that, all my sensors were clean.

So now I have myself a little predicament....I don't know which e30 to keep or which one to part....this 318 I just got runs exceptionally well and revs very well. Needs an alignment and some body work, but over all it seems pretty solid. The body work is pretty big though with the front fender taking a beating and the rear quarter panel getting smashed pretty good. I can probably pull the dents out, but it won't look pretty. Lol. The positive is that the cars rear lsd diff works beautifully and the clutch is nice and grabby.

Or do I try to bring the 323 back.... its kind of a lost cause the more I look at the 323 because the rust is so bad. I didn't realize how bad some of it was.

Or do I just part both out and try to find something better
