What\'s wrong with my Ultra-G?
I recently got a CMG Infinity Ultra-G, and decided to perform a very unscientific run test comparing it to my 2 other Ultras, and one standard Infinity. I guess this test was partially a test of different battery types as well. In the Ultra-G I put a lithium AA, in one of the Ultras, I put an Everactive (Walmart) alkaline AA, and in the other Ultra, I put a Ray-O-Vac heavy duty zinc chloride (not alkaline) battery. In the standard Infinity, I put an Everactive alkaline AA. Well after about 14-15 hours, my Ultra-G was dead, after I fully expected it to totally smoke the other 3 lights. I thought maybe I had a bum lithium cell, so I installed a new lithium cell and continued to time it. Same result. I then tried 2 different alkaline cells in the Ultra-G with the same results, while in the meantime all the others kept shining brightly. It has been just over 51 hours now, and the other 3 lights are still going, with the standard Infinity leading the Ultras (they are both very dim now, but still going.
Anyway I happened to be in the room while the Ultra-G went dead on time. It was bright, and the turned off like I had shut it off (it didn't slowly dim or anything, it just shut off). After playing with it for a while, I discovered that if I give it a minute in the off position, I could turn it back on, and it would glow brightly, but only for a minute, sometimes less. Sometimes if I were to whack it against the table, it would light up, but only to go dark again. Sometimes when it would go out, it would blink on then off, then on, then off. It would do this several times.
Does anyone have any ideas what might be going on here? I tried cleaning the threads with a tiny wire wheel on a dremel in case there was anodizing on the threads creating resistance. Could it be that I simply got one that requres too much current?
Any help would be much appreciated. Thanks.
