battery drain/gauges

[eurojet@xxxx]

I am finding that when I don't drive my D and let it set for two 
weeks that I need to jump start it. I have an Interstate battery 
which is pretty new. My other cars don't have this problem. Also, 
when I shut off the key some of my guages don't settle all the way 
into their resting positions. Should they all go down or do some stay 
up like the fuel gauge and tach? Sometimes they'll go down all the 
way and then go back up. Could they be draining the battery in these 
positions? What's normal? How do I fix it?
