94 mustang cobra
Once again another prob..geesh! So now my battery light turned on and my volts dropped and dash lights dimmed. So I had the battery (interstate) tested and charged (passed). What else can this be?

Yep. Or voltage regulator (located on the altanator). Those are pretty much all the sexy parts on the charging system.

After I had the battery tested and charged I moved to the alternator. I had it tested at auto zone. 1st test failed, 2nd passed, 3rd passed, 4th failed, 5th failed. So I got a new one. Drove to work today and car ran fine..., but I don't think ive driven enough to really know. I hope I don't have a short somewhere.
I was also thinking about adding another ground to my motor. What you guys think?

Id wait and see if you cured the problem with the new altanator.

Extra ground sounds like a waste of cash. 99.9% it was the alternator. My '93 Escort just pulled that exact trick (working, not, working, not) and its not unusual.

Ok. Well 2 days now and no problems. Knock on wood. Just that darn bbk header still not sealing to head.. head nod.

I had problems with my bbk headers not wanting to seal to my heads as well, I found that using the thicker aluminum gaskets worked.

Is there an easy way of finging out whether its leaking from the head to header or header to xpipe? Today i put the stock header back on and tick was gone... sounded soo dam# good! I miss not having an exhaust leak!

You should be able to look at the header that you took off, on the head side of the flange where it was leaking will be a carbon track. If they are on the car I usually just listen close to where the noise is coming from, and stick my fingers around there to see if I can feel any leaks. If you have some one cover the tail pipe it will usually cause the leak to become very pronounced.
