The spec is 40-60 millamp, it's in the service manual somewhere - I found it by accident but can't find it again.

That's .04-.06 amp. I like the light idea, but I really prefer to insert a DVM in there on the 10 amp scale, pull fuses till it goes away. NOW, there is a car here locally that I pulled every fuse except for the 200 amp one near the battery and I still saw around 310ma. Next time I work on it, I'm going to start taking leads off the tiepoint in the back of the underhood fuse box and see what one it is. THEN I'll just leave it disconnected and determine what item(s) don't work and go after them.
