check ALL of your lights glove box,hatch all of em either your batt is to weak to hold a charge or something is running.

do you have lighted mirrors? check to see if they close correctly shutting off the light in the mirror when they are up. I had that problem in my car... ended up cutting the wire to them, who needs lights on your mirrors anyway... i don't use 'em
stang charging systems (with a 2G) are marginal anyhow. i accept a certain amount of drain, and after two weeks, i would expect a hard start or dead battery, myself. these arent new cars.
my two cents. good luck.

If you suspect a power draw, you can use a simple bulb tester on battery. Unhook the negative terminal, and then use the tester between the terminal and the negative lead. With the car off and all the doors shut, it should not light your tester bulb. If it does, you have a power drain. Please read step 2.
Step 2. -> You have a power drain/draw when you shouldn't
Find a friend, preferably one that isn't an idiot and can follow directions (takes longer without a friend)
Starting with fuse 8 (most common fuse for power drain issues), remove the fuse, check the battery again. If the light goes out then that circuit is the one causing the draw. **Note: Make sure you do this with the doors closed, as certain fuses are always hot, and will be able to have power even with the car off.
Fuse 8 powers most of your courtesy lights and some other jazz.
My power draw was caused by a short in the power lumbar motor of my drivers seat AND my 3rd brakelight was miswired (took me a long time to figure out it was 2 things)

That means that something on the #8 circuit is causing the draw. Now you have a place to start loking for the real culprit. Items such as courtsey lights, add on stereo equipment, alarm systems and sometimes add on instruments can be the source of the drain.
See http://www.veryuseful.com/mustang/tech/engine/images/MustangFuseBox.gif for information on what is on circuit #8
im not sure i follow what you mean by in between. do you mean placing the pointed part between the terminal and the cable? and then grounding it somewhere?

If you have that damned negative cable still connected to the front cover move it to the block. I changed the water pump and timing chain and now the thing charges better. That ground sucks there because those front cover bolts corrode. Try moving your ground and checking the batt and charging system, especially the fuseable links. I love my stang but Ford missed the boat on the electrical system.
