REMOVE YOUR BATTERY BEFORE DOING ANY TESTING!
I read a post from a few days ago about the Grand having some resistance in it's body(I think the person said .5 ohms). I figured it would be about right, as aluminum is not the best conductor. So I was bored and decided to do my own experiment. Having disassembled both my Grands before, I wasnt worried about doing this, but a new owner might want to ask Rob before messing around. First thing I did was measure the resistance of my oldest Grand(5+ months). With the one lead on the threads of the atty connection, and the other on the battery spring, I got .5 ohms, just like the other member found. Now let the experiment begin.....
First, I cleaned both the atty connecter and the spring with a qtip soaked in some 91% iso alc. Remeasured the resistance, still got the .5ohms
Next, I removed the spring and cleaned under it(I have never done that even when I had them apart. If you've ever done this, you'll see that the powdercoat/anodizing goes under the spring, and the only place for it to conduct is through the little screw that holds the spring in. I cleaned the screw really well to and reassembled the Grand. Remeasured the resistance and got .4 ohms, an improvement, but no where near noticeable in vaping.
Then I took the spring back out, cleaned the threas for the screw, then put a dab of Noalox right into the screw hole and reattached the spring. Remeasured the resistance, and now I only got .2 ohms!
That's a .3 ohm improvement, which would most likely be noticeable to most of us.
I tried it out with a well used LR306, and it does seem to hit better than before the cleaning, unless my mind it just tricking me.
I wouldnt think this is necessary to do weekly like you should do on the switch contact, but monthly couldnt hurt.
