No respect these days, and no spark either. This on my 325 Bimmer. Poor thing might be on its death bed and with only 380K on it. I've checked the usual suspects I know of and they all seem to be good.

One thing that puzzles me - the manuals and other help online all say that the coil should register 0.50 ohms between the terminals and 5K ohms between positive and the main tower. I get the latter but consistently get 0.8 between the terminals. It's enough off such that I'm guessing it means something but I'm not sure. 0.8 is the figure given for the 318 IIRC, or 0.82 anyway.

I also hooked a test light on each the pos and neg terminals and each lights up connected to ground, with the key on. One online source recommended cranking the engine while hooked to negative, a flickering test light means faulty coil. I did that and I'm getting some flicker but it's light, seems as though most electric items do a little bit of a fade when running the starter motor.

One other thing, the much vaunted Peake diagnostic tool has been useful for resetting service light indicators but nothing else. Never have I gotten a clue about any problem, but I'm thinking surely now it will give me some help, something like this should show in the computer. I plug it in, hit the right buttons, and I get a large flashing E. My manual doesn't refer to this but their website says it means (Error obviously) that the device is unable to communicate with the computer. It ain't right, I tell ya.
