Ok... backstory... got a .17 amp draw on my battery, and am waiting on the alarm company to email me back as to the power consumption of the alarm system I have on the car now.

Anyway... my battery is getting on the lower end of the 'charged' scale as it sits in the car today, and I go out to start it, and it cranks really really slow.. tach keeps moving upwards slowly so I left it crank to see what it would do.. tach swept up past 4000.. then I figured I was heating up my starter, battery , and cables pretty good at that point, so I let off the starter.

Then I go to turn it again, and it seems as if the battery just got some extra juice, because the car is turning over twice as fast as it was before. Weird.. so I let it crank a few, mash the pedal to clear out the fuel, and let off the starter again.

The next time I turn the key, its faster than the other two times, pretty close to "normal" and she fires right up... but... my battery light was on.. until I blipped the throttle, then the interior electronics "pop" on like I just turned the key on....

I'm going to put some new cables on, and charge that battery up again... then see if I can't get it load tested or something... it's a 900amp, and only a year old.. shouldn't be bad, but who knows...

Isn't there a way that the "field" in the alternator or starter can leak ? Maybe its too early but I want to say there's a way voltage can leak out to ground thru an "electric motor".

This is the last of my little issues with this car, and I'd like to figure this out... thinking I might get under the hood, and clean up all the grounds again.. I wonder if my ECU ground might be bad... not really sure tho... feel like I've been over all the obvious stuff already..

Edit: Now a little more direction... I did find out the circuit in question is #8 from the fuse panel inside. Which not having a book handy... it appears its the interior light circuit.

Now considering every light works that I can see, could the .15 amp draw be coming from a bad dimmer switch? I figure its like all Fords... and I could have a short in the headlight switch, MFS, any interior wire... all of that...

One thing that might help to diagnose... I had an issue with this before I swapped everything over to the 93... so I would doubt that it's an inside wire issue.. more so a switch or something in the dash....


Also for those of you reading this.... I found a neat little testing tool.. I'll post another link later.. but if you pull the buzzer out of a newer GM... or older even... they work really well to hear a short if you have one.. :)
