Well I tried this in a variety of ways and I am having problem making it work on my new Ego_C batteries. The repaired atties works great with my old Ego batteries but when I try to use them with my new batteries that I got last week it doesn't work at all. The battery flashes a couple of times and shuts off. I have tested my repaired atties with a volt meter and there is no short. So I don't know what is going on.
