Electrical Engineering/Electronics: Battery Holder & 9V Snap Connector

[PwNakahn]

Hey everyone,

I just went to Radio Shack and picked up a few parts to begin a book on Electrical Engineering/Electronics. I'm taking it slow and trying to understand the theory behind everything before I progress - something simple has got me confused though.

I have two parts:

• Battery Holder (4x AA) w/snap connector (http://www.radioshack.com/product/index.jsp?productId=2062239)
• 9V Snap Connector (http://www.radioshack.com/product/index.jsp?productId=2062218&clickid=prod_cs)

The battery holder is putting out an expected 6V when I test with a multimeter. However, it is putting out no voltage with a 9V snap connector. The 9V snap connector does produce voltage when connected to a single 9V battery. Is there a reason I can't use this connector here? I couldn't find much information regarding this question on Google. Thank you in advance!

There's nothing in the connectors that will make any distinction between 6V and 9V. They are just dumb pieces of metal. I would guess that it is physically making contact somewhere that it shouldn't. Maybe the wires are being shorted out, etc.

Since connecting to the battery holder gave me no read, I decided to connect the snap connector via alligator clip test leads. This measured 6V, as you said it should. All in all, I pulled around on the wires and cleaned the connections and managed to get it to work with the 9V snap connector directly to the battery holder. It seemed to be a fluke of some sort, confusing my newbie mind. Thank you for the quick help!
